Discover how to choose the right maternity bra, underwear, and lingerie for each trimester. From comfort to nursing, we cover it all.
Pregnancy is a beautiful journey that brings significant changes to your body, and your lingerie needs evolve just as quickly. What worked in your first trimester may not offer the support or comfort you need in your third. That's why investing in the right maternity lingerie is essential for your well-being and confidence throughout all nine months and beyond.
In this guide, we'll walk you through what to look for in maternity bras, underwear, and loungewear for each trimester. We'll also share practical tips on sizing, fabric, and nursing-friendly features, so you can feel comfortable and supported from bump to baby.
First Trimester: The Early Changes
During the first trimester, your body begins to produce more estrogen and progesterone, which can cause your breasts to feel tender, swollen, and heavier. Many women find that their usual bras become uncomfortable, and underwires may start to dig into the ribcage. This is the perfect time to transition to softer, more flexible options like wireless bras or bralettes.
Look for maternity bras with wide straps and a stretchy band that can adapt to your growing ribcage. A bralette like the All Lace Bralette offers gentle support without underwire, making it an ideal choice for early pregnancy. Its lace design is both breathable and stylish, so you can feel beautiful even as your body changes.

Underwear is also a consideration. As your belly begins to expand, you may prefer low-rise styles that sit below your bump. The Talco Low Rise Thong is a comfortable option that won't put pressure on your abdomen, allowing you to move freely throughout the day.
- Choose wireless bras or bralettes with adjustable straps.
- Opt for low-rise underwear that sits below the belly.
- Look for breathable fabrics like cotton or bamboo.
Second Trimester: Growing Bump, Growing Needs
By the second trimester, your bump is more pronounced, and your breasts have likely grown significantly. This is the time to invest in more structured maternity bras that offer additional support. A bra with wider underbust bands and full coverage cups can help distribute weight evenly and reduce back pain.
The Le Stretch Lace Demi Bra is a great option for this stage. Its stretch lace adapts to your changing shape, while the demi coverage provides a flattering silhouette under clothing. The adjustable straps allow you to customize the fit as your body continues to evolve.
You may also want to start thinking about nursing bras, even if you're not planning to breastfeed. Many maternity bras double as nursing bras, with clips or drop-down cups that make feeding easier later on. This can save you money and hassle in the long run.
- Consider bras with drop-down cups for future nursing.
- Look for wider underbust bands for extra support.
- Try on bras with the same weight gain you expect to gain.
Third Trimester: Comfort and Readiness
In the third trimester, your bump is at its largest, and your body is preparing for childbirth. Comfort becomes paramount. You may find that even your maternity bras feel restrictive, especially if you're carrying high or experiencing rib pain. This is the time to prioritize soft, seamless, and highly stretchable fabrics.
Consider seamless bralettes or wireless bras that provide gentle support without any pressure points. The Abrima Bralette is a beautiful choice, offering a soft, stretchy fit that moves with you. Its elegant design means you can wear it as a top or under clothing, making it versatile for those final weeks.
For underwear, you might prefer high-waisted styles that cover and support your bump, or you might stick with low-rise options. The key is to choose soft, breathable fabrics that won't irritate sensitive skin. The Never Say Never Comfie Cutie Thong is made from a buttery-soft microfiber that feels amazing against the skin, perfect for daily wear.
- Opt for seamless, tagless underwear to prevent chafing.
- Choose bras with front-closure for easier nursing access.
- Invest in sleep bras for nighttime comfort.
Postpartum and Nursing: Beyond the Trimester
After your baby arrives, your body continues to change. Your breasts may become engorged, and you'll need easy access for nursing. Nursing bras with drop-down cups or front clasps are essential. Look for styles that offer good support but are also easy to open and close with one hand.
The Coccinelle Triangle Briefs are a great postpartum underwear option. They are soft, stretchy, and sit comfortably below your belly, making them perfect for recovery. Pair them with a comfortable nursing bra, and you'll feel prepared for the demands of new motherhood.
Remember, your body will continue to change for several months after birth. It's wise to buy only a few nursing bras at a time and invest in more once your milk supply stabilizes. This way, you won't waste money on bras that may not fit in a few weeks.
- Buy nursing bras in a size up from your current size.
- Choose underwear with a high cotton content for breathability.
- Have at least two or three nursing bras in rotation.
Fabrics and Features to Look For
When shopping for maternity lingerie, fabric is just as important as fit. Breathable, moisture-wicking materials like cotton, bamboo, and modal are ideal because they help regulate body temperature and reduce the risk of irritation. Look for bras with seamless construction to avoid rubbing against sensitive skin.
Adjustable features are also crucial. Your ribcage expands during pregnancy, so bras with multiple hook-and-eye closures or adjustable straps can accommodate your changing size. Similarly, underwear with stretchy waistbands that sit below or above the bump can provide comfort without digging in.
Finally, consider the style. Just because you're pregnant doesn't mean you have to sacrifice style. Many maternity bras and underwear come in beautiful lace designs and soft colors, so you can feel confident and feminine throughout your journey.
- Choose fabrics like cotton, bamboo, or modal for breathability.
- Look for adjustable straps and multiple hook-and-eye closures.
- Don't be afraid to choose stylish pieces that make you feel good.
Maternity lingerie is an investment in your comfort and well-being during one of the most transformative times in your life. By choosing the right bras and underwear for each trimester, you can support your changing body and feel confident every step of the way. Remember to prioritize comfort, adjustability, and breathable fabrics, and don't forget to treat yourself to a few beautiful pieces that make you feel special.
