When should you buy a maternity bra?

Pregnancy is a transformative journey, both emotionally and physically. Among all the changes your body goes through, one of the first you’ll notice is the transformation of your breasts. They become more sensitive, fuller, and sometimes even painful. That’s where a maternity bra comes in: a precious ally that supports your body with comfort and gentleness.
But when should you buy a maternity bra? And how do you choose the one that best suits your needs? Mama Hangs is here to guide you every step of the way—so you feel supported, in every sense of the word.

What’s the difference between a maternity bra and a nursing bra at Mama Hangs?

At Mama Hangs, we believe your lingerie should adapt to you, your needs, and your unique motherhood journey. That’s why we don’t draw a strict line between maternity and nursing bras. Our designs are made for all moms-to-be:

  • Those who plan to breastfeed,

  • Those who are still undecided,

  • And those who don’t plan to breastfeed but want absolute comfort during pregnancy and postpartum.

Toward the end of pregnancy, some women experience milk leakage (yes, it happens!), even without planning to breastfeed. That’s why Mama Hangs offers two main solutions to support your needs:

  • The Everyday range: our ultra-comfy bralettes made from breathable, stretchy micromodal, that feel like a second skin and follow your breast’s natural changes without restriction.

  • Our three ranges of absorbent and waterproof maternity lingerie: the Essential Bra, Mama Glow, and Day'n Night—designed to discreetly manage leaks before, during, and after baby’s arrival, whether you breastfeed or not.

With Mama Hangs, one guiding principle: to support you gently at every step—without ever compromising your comfort or style.

When should you buy your first maternity bra?

It’s a common and important question! We generally recommend buying your first maternity bra around the start of the second trimester, between 12 and 20 weeks of pregnancy.
At this stage, many women notice a significant increase in breast size. Your breasts become heavier and more tender. Wearing a regular bra can quickly become uncomfortable or even painful.
A well-designed maternity bra will provide the support and comfort you need to stay active and at ease.

Why a second maternity bra purchase is helpful before birth

As you approach the third trimester—especially around the 8th month of pregnancy—your body continues to change in preparation for your baby’s arrival. Your breasts, in particular, may go through another growth phase and become even more sensitive. That’s why we highly recommend investing in a second maternity bra at this stage.

Why? Because the first bra you bought earlier in your pregnancy might now feel too tight or less comfortable. By anticipating this change, you ensure a better fit and continued support during those last weeks—without discomfort or compression.

It’s also a great opportunity to choose a maternity bra that can double as a nursing bra, even if you're still unsure about breastfeeding. Some women experience colostrum or milk leaks at the end of pregnancy—even if they don’t end up breastfeeding. At Mama Hangs, we’ve thought of every situation.

Our maternity bras, like the Mama Glow or Essential Bra, are stretchy, ultra-soft, and equipped with absorbent and waterproof features. They’re made to discreetly manage leaks while keeping you completely comfortable. Their breathable micromodal fabric hugs your curves without compression—for total well-being.

By choosing the right model, you’re preparing your body for the natural fluctuations of motherhood—while enjoying lingerie that’s reliable, comfortable, and beautiful, before, during, and after baby arrives.

Which maternity bra should you choose?

For daytime: comfort, support, and adaptability


During pregnancy, your breasts constantly evolve. So, it's essential to choose a wireless bra that’s breathable, soft, and able to adapt to these changes. All Mama Hangs bras feature a wide elastic band under the bust—it’s this band that ensures proper support, even for fuller busts. Contrary to popular belief, straps aren’t meant to carry the weight of your breasts, as that would cause tension, discomfort, and back and shoulder pain.

For a simple, ultra-soft option that adapts perfectly to size fluctuations, our Everyday bralettes are ideal. Made from super-stretchy micromodal, they offer a second-skin feel and will support you well beyond baby’s birth. Their natural, breathable fabric guarantees daily comfort.

If you’re looking for a maternity bra that combines support, softness, and leak protection, check out our Essential Bra or our Mama Glow. These models are specially designed to absorb late-pregnancy leaks—and will become your best allies if you choose to breastfeed.

Special mention for the Mama Glow, which features six rows of hooks for ultra-precise adjustment as your body changes. Thanks to their stretch, breathability, and absorbent-waterproof technology, our maternity bras are designed to be worn all day long—without discomfort, even during major size changes.

For nighttime: lightness and softness above all


At night, when your breasts feel heavier and more sensitive, comfort should come first. Wearing a maternity bra while you sleep can help ease breast pain and support your bust as you move.

For this, our Everyday bralette is perfect: light, soft, seamless, clip-free—it feels invisible and gently hugs your body. If you prefer a model that combines softness and absorption, our Day’n Night bralette is your best friend. It wraps you in comfort while protecting your skin and bedding from any night-time leaks. And for even more comfort, the Day’n Night range also comes in a top version, for full support with total softness.

Thanks to these specially designed maternity bras, you can navigate every stage of pregnancy and postpartum with comfort and peace of mind.

Why avoid underwired bras during pregnancy?

Underwired bras might seem appealing for their support, but they’re often too rigid for a changing bust. They can compress milk ducts, increase the risk of engorgement, or even lead to inflammation (mastitis).

A stretchy, soft, and well-fitting maternity bra respects your breast’s natural shape and supports its health throughout pregnancy.

The maternity bra: essential for relieving breast pain

From the first weeks, breasts often become extremely sensitive. A good maternity bra cushions movement, supports without constricting, and reduces daily discomfort.

Choosing the right bra isn’t just about comfort — it’s also about taking care of yourself, your posture, and your overall well-being during this unique time.

Support your changing bust without switching sizes

At Mama Hangs, we understand how hard it is to anticipate every change in your body during pregnancy. That’s why we’ve designed our maternity bras to adapt to you — not the other way around.

Made from plant-based micromodal fabric, our bras are ultra-stretchy, breathable, and soft against the skin. Flexibility is at the heart of our design: stretchable cups, comfortable underbust bands, and on the Mama Glow model, six rows of hooks across three levels to adjust support month after month.

Many of you will find one size is enough throughout pregnancy — and even after birth. No need to keep buying new bras: a single, well-designed maternity bra will support you before, during, and after your baby’s arrival.

A smart, sustainable, and comfy investment to enjoy motherhood with ease.

Why choose Mama Hangs for your maternity bra?

  • Flexibility and adaptability: designed to naturally follow your body’s changes.
  • Premium materials: soft, antibacterial, and hypoallergenic micromodal fabric.
  • Seamless design: to prevent irritation and marks on your skin.
  • Elegant style: proving you can be pregnant and stylish at the same time.
  • Eco-conscious commitment: all our bras are made of breathable micromodal from FSC-certified beechwood cellulose.
