When you’re expecting a baby, finding the perfect bra might be a lifesaver. Luckily, it’s easy to accomplish. We know how much our boobs vary during pregnancy and breastfeeding, so we’ve made it easy for you to check your size as often as you’d like.

When it comes to finding the correct bra size, there’s never been a better moment. Let’s go discover yours right now.

The following factors should be taken into account when determining whether or not your bra is providing you with the optimal fit:

  • Adjust the straps so that they are snug but not painful on your shoulders.
  • There should be no spilling or gaping between the cup and your breasts.
  • Center front: The center of your bra should rest flat on your chest at the center point on the front. In order to avoid discomfort, it should not dig in or rise above your chest.
  • It’s important that your band sits flat and comfortably around your body.

If your bra just doesn’t fit like it should, try our bra calculator to find your recommended size or head on over to our fit troubleshooter or fit FAQs for additional help. Alternatively, if you’re still undecided, you may contact us at [email protected] to speak with one of our fitters.

Why Do I Need a Maternity Bra?

Everything in your body, including your breasts, expands and swells as a result of pregnancy. Throughout your pregnancy, you’re likely to require a new band and cup size. It’s because of the following reasons(2):

  • Shifts in the ovaries.
  • Weighing more
  • Expansion of the ribs
  • Swelling.

How to find my maternity bra size

Following these four simple steps can help you determine your bra size, or you can use our free Find my fit quiz to get an idea of what size you need. Alternatively, you can look at our instructional films for all things fitting, especially while pregnant. They will be of great assistance to you.

As a reminder, we recommend getting a professional bra fitting if at all possible, especially if you’re pregnant. To ensure that you get the right size and style, you should keep in mind that breast changes might occur quickly during pregnancy.

STEP 01:

Take a tape measure to your underbust (band)

Measure around the band of the bra while wearing a non-padded bra. Our universal sizing system will be used to take your measurements, and we will then convert them for you in Step 4.

The tape measure must be level and snug. It should not budge. Take the next whole number as your starting point for the calculation. If your measurement is 27.4 inches, round it down to 27 inches. To put it simply, your band size is 30.

To find out what size generic band you need, use the measurement categories listed below. You’ll need this information in the future, so keep track of it.

STEP 02:

Take a bust measurement (cup)

Now, with the same care you used in the previous step, take a measurement all the way around your breasts, at their fullest.

The following whole number should be rounded off. You can round up to the nearest whole number if you have a bust measurement of 34.6 inches. Keep this number in mind.

STEP 03:

Make a cup sizing calculation.

Your ‘Cup Size’ is the result of subtracting your ‘CUP’ measurement (in inches) from your ‘Universal Band Size’ measurement (in inches).

If you have a 35″ cup and a 30″ band, your cup size is a DD, and you should order a 30DD.

STEP 04:

Take your discoveries and convert them into something useful.

Please make a note of the band and cup sizes you measured and put them in the appropriate fields below (eg 32FF). Click the ‘Show me my cup and band size’ button to get your measurements.

Everything you need to know

When is the best time to buy a maternity bra?

Maternity bras can be purchased as early as possible after conception. Breast pain is common in the first few weeks and months of wearing a bra, therefore we recommend opting for models that are wire-free and seamless. With the intention of breastfeeding in mind, we propose that you choose nursing bras instead.

When’s the best time to buy a nursing bra?

At any point throughout your pregnancy, you can purchase nursing bras, and then use them to breastfeed your child once he or she is born. If you plan to exclusively breastfeed your baby, we recommend having the nursing bra fitted around 8 months into your pregnancy.

Who should be aware of the most prevalent fit issues?

The back band is either excessively tight or slack.

Either the straps are too loose or too tight (cutting in)

Too big or too small a cup restricts breast tissue (gaping)

How can I tell if my nursing bra is fitted correctly?

You won’t have to worry about the band riding up, since it will fit snugly but comfortably around your body. Should your breasts leak out of the top, sides or bottom of your cups when you wear a bra? There should be no wrinkles in the cloth or gaps in the cups.

Smooth bra cups and a wire that fits neatly under and around the breasts are essential. The most crucial criterion for determining whether or not a bra is a good fit is whether or not it feels comfortable.

How many nursing bras do I need?

The three bra rule states that you should have three bras: one for wearing, one for washing, and one for storing.

What’s the best nursing bra for me?

The answer to this question depends solely on your lifestyle and personal taste. Bras that are seamless or wireless are great for sleeping in, lounging around, doing light exercise, or using as a transitional piece when your breasts are still growing.

T-shirt wearers who want a bra with a sleek underwire shape may like contour bras.

Sports bras are intended to provide additional support for the breasts during activities ranging from low to high impact.

Women who want to look their best while still getting a little extra support may consider investing in a flexi-wire bra.

How to Fit a Nursing Bra: 3 Mistakes Moms Make Bra Shopping

It’s all too usual for new parents to neglect to buy a great nursing bra, even though they have everything else they need for the infant.

Don’t wait until you’re in pain to start making money. If you want a better breastfeeding experience, now is the time to learn how to properly fit a nursing bra to your body.

There is more to a decent nursing bra than simply being “an underwire-free bra.” In order to get the best-fitting breastfeeding bra, look for one composed of soft, elastic, and non-abrasive materials. We’ve put together a list of the most common mistakes mothers make while shopping for a new bra, so you can avoid them.

Nursing bra buying guide (Before You Buy series) | Video | BabyCenter

1. Shopping too soon

Each pregnancy and each woman is unique, so it’s hard to predict how your breasts will respond. Some moms report a little increase in cup size, while others report a four-cup size increase.

Three to four months following the birth of your baby is the ideal time to begin sizing yourself for more structured nursing bras, according to many experts. Midday, when the breasts are full, before a feeding, is the greatest time to measure.

Try to wait until you’re about eight months pregnant before buying nursing bras. All but a few pounds and most of your baby weight will have been gained by then. When your body has learnt to regulate its milk supply, the size of your breasts at eight months should be similar to the size of your breasts eight weeks after giving birth.

2. Putting up with an uncomfortable bra

When shopping for a nursing bra, look for one that is able to expand and contract with your body as you breastfeed throughout the day and night. For the first few weeks, you’ll be wearing a bra nearly every day and night, and therefore it’s imperative that the fabric is comfortable. Avoid anything that could cause an allergic reaction.

There is a nursing bra sizing chart or calculator for each brand. This means that even if you used another website to get your measurements, you should always double-check the store’s website to make sure your estimate is correct.

A bra size chart and your measurements can help you determine what size to order, but the real test comes when you arrive home and put the bra on. That’s what you want to feel like when you put on your new bra. Under your breasts, the band should be level with the bottom of your bra. It should be snug but not too tight.

Sit down and give it a whirl. Stand up and see how many people are there for you. Bend your knees and lie on the ground. No bra should slide down your back.

To avoid this problem, many women purchase a bra that has too much space in the cups. Unlike regular bras, most nursing bras are composed of an elastic material that can tolerate changes in size, so you don’t have to go up several cup sizes.

3. Forgetting other styles

Nursing and maternity bras come in a variety of styles, just as clothing for different occasions. When it comes to resting, reclining, and going out, a high-quality nursing bra may be all you need for some ladies. Having a variety of bras (pumping bra, strapless bra, sports bra, etc.) will make this stage of life much more comfortable for most women.

Some women question if they need both a nursing bra and a pregnant bra, and if so, what the difference is. Nursing bras, on the other hand, include unique apertures that make it easy to nurse. You can slide your breasts out of our French Terry Racerback Nursing & Sleep Bra, while our full-coverage Simply Sublime Nursing Bra incorporates clip-down cups.

In addition, keep in mind that your requirements may evolve over the postpartum time. You’ll probably be spending a lot of time at home throughout the first several months of your pregnancy. You’ll need a material that is soft, smooth, and stretchy, with a wide range of sizes and easy access to the breast. Later, when you start going out more, you’ll want a more structured bra with contoured cups, more strap support, and sexier style that looks wonderful under your apparel.

As soon as you put on an early breastfeeding bra, such the Organic Cotton Crossover Nursing & Sleep Bra or the Marvella Nursing T-shirt Bra, you’ll notice the difference in comfort and support.

We hope this Nursing Bra Buying Guide was useful in helping you select the perfect nursing bra! Our first priority is making you and your new baby feel at ease, so you can enjoy your time together.

Bonus: How to measure for a nursing bra

When it comes to getting a proper fit, correct bust measurements are essential If you don’t have a soft measuring tape, you can use a ruler and a ribbon, scarf, sash, or belt to measure your waist.

Start by measuring your underbust in order to determine your correct size. Under your breasts, this is the area around your rib cage. The tape measure should be snug but not tight.

Underbust measurements should be rounded to the nearest whole number. Your band size is determined by this rounded number.

Get a measurement of your bust at its largest point. Snugly place the tape measure across the widest area of your breasts and wrap it around your back a few times.

Then deduct your bust measurement from your band size. One cup size is equal to one whole number difference. A B cup is defined as a two-inch difference, a C cup as a three-inch difference, a D cup as a four-inch difference, and so on.

If your underbust measurement is 37 inches, round it up to 38 inches. A cup size of F corresponds to a bust measurement of 44 inches at the fullest point.

Given these measurements, the correct bra size is 38F, which is an XL-Busty in most Kindred Bravely bras (see each bra’s size chart to get the right bra size).

You know your bra is too big if:

  • Your breasts protrude from the band’s bottom.
  • In the back, the bra band rises.
  • Wrinkles appear in the bra cup.
  • Despite the tightest setting, the shoulder straps fall off the wearer’s shoulders.

Your bra is too small if:

  • Breasts protrude from the sides or the top of the cup in mounds.
  • The bra “pokes” you in any direction.
  • Instead of lying flat, the center has a tendency to rise.

Even while we don’t normally advocate an underwire bra during pregnancy, if you have enormous breasts, your options may be limited. Not all elastic cups can keep you in place all the time.

12. Carriwell GelWire Maternity Nursing Bra

This new “gel wire” bra provides support without causing discomfort or injury during pregnancy and breastfeeding. In order to protect breast tissue, the supplied gel molds around breasts, but it is still malleable enough to be moved around when your body shifts.

With this one, you won’t have any issues with it rubbing against your belly, and it wicks sweat away from your skin to keep you cool. When you’re working out while pregnant, all of those factors are far more important than whether or not the equipment is labeled as maternity.

18. AKAMC Removable Padded Maternity Sports Bras

These bras include replaceable cups and are constructed of a breathable, moisture-wicking fabric.

What are maternity bras – and do I need one?

When you’re pregnant and your breasts are expanding, you’ll need a special type of bra to keep them in place. Wider straps, a soft cotton lining, and extra hooks and eyes on the band are all common features of pregnancy bras. Underwire is optional in some styles, while it is required in others.

Pregnancy bras are a definite necessity. Your breasts, like the rest of your body, are expanding and growing more sensitive throughout pregnancy. Hormonal changes, weight increase, a growing rib cage, and the development of milk-producing mammary glands later in pregnancy all contribute to this transformation.

Even though you may be tempted to save money by using your current bras (after all, you already have maternity clothes!), you should instead invest in a few high-quality pregnancy bras. There is a good chance your breasts are getting heavier due to the development of glandular tissues, which can add a couple of ounces to each breast at least.

When should I start buying maternity bras?

Pregnancy bras should be purchased as soon as your usual bras begin to cause discomfort or tightness. When you’re six weeks pregnant, for most women, this begins to occur. Bras that don’t fit well, have indentations were their bands and straps were, or if your breasts are spilling out of the cup, are time to buy a new one.

In the end, your breasts will change in a way that is unique to you as a result of pregnancy. In certain cases, the size of your cup may continue to develop throughout your pregnancy, or your breasts may grow during your first trimester and then not grow again until your milk supply begins to increase in the final few months. During your pregnancy, you may find yourself needing to buy new bras more than once.

What’s the difference between maternity bras and nursing bras?

Nursing bras include clasps or panels that provide easy access to the nipples for breastfeeding, whereas maternity bras don’t have this capability. Breastfeeding bras come in various shapes and sizes, including nursing sleep bras, nursing sports bras, and more.

Maternity bras or larger sizes of their favorite pre-pregnancy bras are often purchased early on in the pregnancy, while nursing bras are typically switched over in the third trimester. Late in pregnancy, when you may be feeling uncomfortable and weary, nursing bras that provide soft, wire-free support can be a great solution for your problems.. Additionally, if you choose to nurse your child, you’ll require these items after the birth of your child.

Postpartum nursing bras can be purchased around 36 weeks of pregnancy. Buying nursing bras during pregnancy is fine, but make sure there is enough room for your breasts to expand. After your baby is born and you start producing milk, your rib cage will continue to expand, and your breasts may increase in cup size by a cup or two. Choose a bra that fits while the clasp is at its tightest position, so that you can loosen it.

How many maternity and nursing bras do I need?

Pregnant women often need three maternity undergarments, as well as three nursing undergarments, while breastfeeding (so you have enough to wash and wear). Sports bras and other unstructured, soft-sided bras may be able to serve as a substitute for maternity bras in the early stages of pregnancy.

Buy a bra extender, which is a terrific method to extend the life of your bras. It hooks into the band of your bra and attaches to the back for added length. It’s a cheap method to extend the life of your pre-pregnancy or early-pregnancy bras, which can be found online for under $5 each.

You might also ask a sister or a friend who is expecting a baby of a comparable size whether she has any maternity bras she no longer needs.

How to find the best nursing bras and maternity bras

Looking for the finest nursing and pregnancy bras? Ask your friends, try on different styles until you discover your favorite, and check out our selections for the best nursing bras and best maternity sports bra.

The easiest way to discover the most comfortable fit is to try on several different styles and sizes when shopping in person. Free measurements are available at lingerie specialist boutiques. Don’t forget to compare your measurements to a brand’s size charts while purchasing online — you can always return what doesn’t fit.

Sturdy seams and straps are essential in nursing bras and maternity bras; fragile ones just will not hold up. Make sure that the bra you purchase has straps that are at least an inch wide at the shoulders if your breasts are larger than a DD cup.

There should be no bunching, pinching, or sliding while standing or sitting. Bras that don’t fit properly are those in which the chest band protrudes into your breast area, the cups overflow (or gap), or the straps slip off your shoulders despite your best efforts at adjusting them. Wearing an uncomfortable bra can only become worse over time, so it’s best to avoid them at all costs.

Some pregnant women prefer to wear soft cups instead of underwire bras since they are more comfortable and don’t pinch their breasts. It’s best to look for garments made of a material that is both soft and free of seams, such as a blend of both cotton and synthetic.

These days, you can get everything from ultra-sexy lace bralettes to cotton ones with soft cups in adorable patterns in the category of nursing and maternity bras. Even if you decide to go with your pre-pregnancy lingerie style or something completely new, you’ll have plenty of alternatives to select from.

How do you measure for a maternity bra?

Measure around your back and under your armpits using the measuring tape. Above your breast tissue, place the measuring tape. Make sure the measuring tape is parallel to the floor behind you while staring in the mirror. Exhale and check to make sure there are no fingers under the tape.

When should I start wearing a maternity bra?

Maternity/nursing bras should be used as soon as you begin to detect changes in your breasts, which is usually around the end of your first trimester.

How many sizes do you go up during pregnancy?

Order one size higher if you are attempting to get pregnant at the time of purchasing your bridesmaid dress. If you get pregnant, you’ll have plenty of room to grow into your dress on your big day.

Should I wear a bra at night while pregnant?

During pregnancy and breastfeeding, you should wear your maternity bra at night if you prefer to sleep without it. As a matter of fact, it is entirely up to you whether or not you wear a bra.

Do you have to wear non wired bras when pregnant?

As long as the wire doesn’t dig in and the bra still fits, you won’t have to give up your underwired bras while you’re pregnant. Non-wired bras, on the other hand, are preferred by certain women for their comfort.

Do breasts go back to normal size after pregnancy?

Dr. Kolker indicated that the glandular parts of the breast swell significantly during pregnancy, resulting in an increase of one or two cup sizes. When a woman goes through childbirth, her breasts return to their pre-pregnancy size or a little less.

Is a Maternity Bra the Same as a Nursing Bra?

Some nursing bras can be worn as pregnancy bras, however maternity bras are not nursing bras.

Is that all clear to you now?

As your breasts get bigger and heavier, you need a maternity bra to help support them. In a similar vein, nursing bras are made to accommodate larger, milk-filled breasts while also providing a convenient means of exposing the nipple without removing the bra in order to promote breastfeeding. In most nursing bras, the breast is exposed by means of a clasp, clip, panel, or other mechanism


A nursing bra can be worn as a maternity bra with no issues. The size of your breasts will fluctuate dramatically as your pregnancy progresses and throughout the postpartum period, so it’s not a good idea to invest in a beautiful nursing bra simply because you think you’ll use it for months.

How to Choose the Right Nursing Bra for You - Baby Chick

Your breasts may swell immediately after delivery, and when your milk starts coming in, they will be a whole different size. You can, in fact, measure two different cup sizes in a single day. When your kid is four months old, your milk production will begin to dwindle, and you’ll likely need a new bra.

You should not purchase a maternity bra because you believe it will meet a future requirement for support and comfort, but rather because it meets your current need at the time of purchase. Even if your pregnant bra has a nursing panel, there’s no assurance that it will fit you again at some point.

How Many Maternity Bras Do I Need?

Buying a whole wardrobe’s worth of maternity bras at once is not something we advocate, even if you know you’ll need them for the duration of your pregnancy. The reason for this is that your body changes over time, so what fits now may be too tight in a month or two.

When it comes to maternity bras, it’s advisable to buy two or three and rotate them between washes and wears. Then purchase a further two to three.
