The biggest question that pregnant mothers pose is what maternity bra size to wear. When you are pregnant, your body changes amazingly, and one of the first things to change is your breasts, which start to feel different and grow. The right maternity bra may change your universe in terms of comfort, support and confidence, as your body changes.
In need of supportive and quality brassieres, you can consider a variety of Momcozy maternity lingerie that is planning to expand with you and make your transition easier. In this guide, you are going to be taken through the steps of finding your perfect fit step-by-step.

Why Your Regular Bra Size May Not Work During Pregnancy
The type of bra that you often use can be tight, uncomfortable, and even painful as your body gears up for breastfeeding. Pregnancy leads to a hormonal imbalance that makes your breasts increase in size, your ribcage expand, and your skin become more sensitive.
Conventional bras do not have the flexibility and support required in these changes. Maternity bras are made in such a way that they have additional stretch, wider bands and soft material to grow with the body and to avoid pain.
The major variations between maternity bras and regular bras:
- No underwires or specially made wires are used to ensure that the sensitive breast tissue is not pressed.
- Broad bracelets and belts are more supportive.
- Breathable soft fabrics to minimize irritation.
- Cups that are flexible and fit the fluctuating breast sizes.
When and How Your Body Starts to Change
The majority of women experience growth of the breast during the first trimester, at times as early as six weeks of pregnancy. Several moms-to-be are forced to retire their regular bras by the second trimester.
Changes to expect:
- First trimester: Slight growth and tenderness.
- Second trimester: The growth in size and fullness is evident.
- Third trimester- Further development and milk production preparation.
One suggestion that one can make is to be fitted with a maternity bra at the beginning of your pregnancy and reevaluate every few months as your body alters.
How to Measure Your Band and Bust Size at Home
It is easy to gauge yourself in the house and be sure of the correct size. All you require is a measuring tape of soft type.
Step 1: Measure your band size
- One should place the tape measure around the ribcage, right under the bust.
- Ensure that it is tight yet not too tight.
- Round off to the nearest whole number.
- In case it is an even number, it should be 4 inches more. If odd, add 5 inches.
Example: 31 inches + 5 = 36 (band size 36).
Step 2: Measure your bust size
- Wrap the tape around the fullest part of your bust.
- Make the level of tape comfortable.
- Round off to the nearest whole number.
Step 3: Calculate your cup size
Calculate the difference between the band measurement and the bust measurement.
The distinction defines the size of your cup:
- 1 inch = A cup
- 2 inches = B cup
- 3 inches = C cup
- 4 inches = D cup
- 5 inches = DD cup

Using a Maternity Bra Size Chart for Accurate Fit
When you know your band size and cup size, consult a chart of sizes of maternity bra sizes. These charts can assist you in matching your measurements with the correct size of the bra, and they also take into account the changes that occur during pregnancy.
Other maternity bras are marked in small, medium, or large instead of the customary cup and band sizes. Then, you can determine the size of the chart offered by the brand on the basis of your measurements.
Signs That Your Current Bra Size Is Too Small
You need to know when your bra does not fit well any longer. A tight, tight bra may make one feel uncomfortable and may even result in blocked milk ducts in the future.
The following are indicators of an increased size:
- Scratches on your skin from straps or bands.
- Leakage on the sides or the top of cups.
- Underwire pinching painful breasts.
- Breathing trouble or limitations.
- And you have to keep changing your bra.
When you notice any of these signs, then it is time to size up.
Should You Size Up for the Third Trimester?
The third trimester may also result in another growth surge in the size of the breast and other rib cage expansion. Quite a number of moms have to move up to one band and one cup size at this stage.
To plan ahead:
- Select bras that have adjustable bands and loose cups.
- When purchasing a new set of bra, buy at least one size bigger than the one that fits you now so as to make up for changes in late pregnancy.
- Seek convertible styles that could be converted into nursing styles as well.
Choosing Bras That Offer Room to Grow
This is because your body will keep on changing during pregnancy and even after delivery, so you should wear bras that are flexible in nature.
Features to look for:
- Various hook and eye closures of variable band width.
- Elastic material that will keep you warm and cozy when you change your cup size.
- Leak protection and customizable fit, removable pads.
- Smooth designs with no irritation of the sensitive skin.
Quality maternity lingerie will help you to have a long life with your bras during pregnancy and breastfeeding.

Tips for Trying On Maternity Bras In-Store or Online
The following are tips that need to be remembered when purchasing maternity bras:
In-store:
- Test positioning by moving about.
- Test the fit of the shirt by lifting the arms and bending forward.
- Ensure that there is no gapping or pinching.
Online:
- You should measure first before you order.
- Look at product reviews as a way of getting the sizing.
- Return of check policy in the event of a need to change sizes.
It can be better to order a bra in one case and then purchase multiple bras in the second case so that you are sure you have the correct fit.
Conclusion
The correct maternity bra size is the secret to being comfortable and well supported during pregnancy. By measuring yourself, learning the modifications of your body and choosing high-quality maternity lingerie, you will be sure to respond to the question, what size maternity bra should I get?
Generally, your size will need to be re-evaluated after a period of a few months, and you should be ready to change as you grow in pregnancy. It will not just make you feel comfortable, but will also help your health and well-being as you prepare to be a mother.
