Pregnancy is an emotional time full of change – both physically and mentally – which is why finding comfortable, supportive maternity wear is vital. In this blog post, we’re sharing everything you want to know about how and when to buy maternity bras. What should you look for? Is a maternity bra the same as a nursing bra? We’re covering it all for you mamas-to-be. 

After reading this post, you’ll feel confident enough to find the perfect maternity bra (or bras) that will carry you through pregnancy and beyond. 

What is a maternity bra

Maternity bras are specially designed for women to wear when pregnant or breastfeeding, as they have features that help support a woman’s body through and after pregnancy. Maternity bras differ from traditional underwire bras in that they support your growing breasts and keep you comfortable as your body expands. To do so, they feature stretchy fabric that allows room to grow as the body changes in shape and size.

Maternity bras also have wider straps for added comfort and sturdy support. They can sometimes have extra hooks to give more size flexibility, and some will also have clips at the cup to allow easy access for breastfeeding post-pregnancy. Not only are maternity bras constructed from stretchy fabrics, but the materials are also soft and breathable to keep you cool and content even in the uncomfortable months of pregnancy. 

Most maternity bras have no underwire since they can be too rigid. Instead, they feature a flexible under-bust band that moulds with you and can accommodate your expanding rib cage. The cups offer plenty of coverage to keep you from spilling out, even as your breasts grow.

What’s the difference between a maternity bra and a nursing bra

Traditionally, a maternity bra was meant to be worn during pregnancy, and a nursing bra was for after birth. This is because nursing bras are designed with clips that allow easy access when pumping or breastfeeding. These days, you’ll often see maternity bras that are also breastfeeding-friendly, so you don’t have to buy separate bras. (Yay!) 

Our Bendon maternity bras have clips that can be used during AND after pregnancy. This means you don’t have to worry about buying as many bras, especially during the busy months before and after you give birth.

Why you should buy a maternity bra

1. Your breasts go through lots of change during and after pregnancy

Your breasts will likely grow during and after pregnancy. It’s common for your cup size to increase anywhere from two to four sizes. Your breast may begin to feel sensitive, heavy, and bigger during this time, and wearing an underwire or any confining bra can restrict that process. If you choose to breastfeed or pump, know that your cup size and shape can also fluctuate throughout that journey.

2. Your body may change shape

Your breasts aren’t the only thing changing during pregnancy. Internally, a lot is happening to make room for a baby, so it’s expected for your body to change shape. For one, it’s common and normal to put on weight during pregnancy. Your rib cage may also widen during pregnancy, allowing the baby space to grow. After birth, your body is still going through changes in size and shape. To accommodate this movement, you may need to opt for a larger band size in your maternity bra than normal.

3. Maternity bras can be more comfortable

All the features maternity bras offer are there to help you feel more comfortable during and after pregnancy. When you’re shopping for a maternity bra, look out for these features: 

Wider straps

Wide straps add extra support and won’t dig into your shoulders. 

Additional hooks

Having a maternity bra with extra hooks means you can adjust the size as needed. 

Soft, stretchy fabric

You’ll be wearing your maternity bras daily, so you want them to be as comfortable as possible. Soft, stretchy fabrics won’t be scratchy, itchy, or restrictive. They’ll bend with your body as it changes.

Full coverage cup shape

Full coverage cups ensure your breasts aren’t spilling out, even as they grow larger throughout pregnancy.


As we’ve briefly mentioned, you ideally want your maternity bra to be wire-free. This will be the most comfortable option day to day as it is forgiving, stretchy, and skin-friendly on sensitive areas. If your maternity bra contains wires, make sure they are soft and flexible to avoid any issues.

4. Maternity bras provide better access for feeding and pumping

If you choose to breastfeed or pump, you’ll need access multiple times throughout the day and night. Wearing a traditional bra that doesn’t contain easy-access clips is impractical and annoying for everyday wear. Instead, opt for a maternity bra with clips to allow for better access. Because you don’t need to take your bra on and off each time you feed, maternity bras will enable you to feed more discreetly if this is important to you.

When to buy a maternity bra

Everyone is different, and every pregnancy is different. So buy a maternity bra when you feel ready. Ideally, they should be purchased when you notice a need for a cup and/or a band size change. This is around the six to eight-week mark for many women as milk ducts start forming in the first trimester of pregnancy

You may also begin to notice your bra isn’t as supportive as it once was or has started to dig into your skin—this is a sign it’s time to swap over to a maternity bra. It’s a good idea to be wire-free from there on out as you need a bra that will be supportive and comfortable throughout pregnancy. There’s also the chance that restrictive underwires and too-tight materials can cause blocked milk ducts, which you want to avoid. 

Whether you buy separate maternity and nursing bras or find one that works for both, it’s worth noting that some mums like to get their nursing bras sorted before the baby arrives, so it’s one less thing to think about.

How to buy maternity bras

Understand how maternity bras should fit

The best way to ensure you buy a maternity bra that’s comfortable is to understand how it should fit. Ensure that the straps do not cut into your shoulders. They should be firm to hold breasts comfortably and distribute weight evenly. The bra band should have some stretch to allow your body to grow. The cups should be full coverage to keep breasts supported and allow for more room to grow. If the back of the bra is riding up, go up a cup size. And, the hooks should be the tightest hook initially so you have room to adjust later.

Buy the right amount of maternity bras

While buying multiple maternity bras at once might be tempting, we warn against going too crazy initially since your size can still change throughout and after pregnancy. Three bras are a great amount to start with. You may leak milk, especially in the beginning, so it’s always good to have backups to work in with laundry day. Consider that you may also want one to wear at night to keep your breasts supported and prevent leaking.

Choose a maternity bra you feel confident in

At the end of the day, you want a maternity bra you feel confident in. You’ll be wearing it most of the time, so choose something that makes you feel good. And no worries, maternity bras don’t have to be ugly. There are plenty of gorgeous colours and styles to choose from, like these Bendon favourites:
