Thirdlove nursing bras are made for the real moments of pregnancy, breastfeeding, and pumping. Whether you need easy feeding access, all-day support, or a smoother shape under clothes, our maternity bras put your comfort first. These are bras built around your body as it changes, not just how they look on a hanger.
Look for a nursing bra with easy feeding access, dependable support, soft breathable fabric, and a fit that adjusts as your body changes. The best styles handle real feeding moments, so you can focus on your baby instead of slippage or leakage. Prioritize the features you can feel the moment you put the bra on.
Here are the details worth checking before you buy:
Start wearing a nursing bra as soon as your breasts begin growing, often in the second trimester, when they need extra support. Your breast size can change a lot during pregnancy and again once your milk comes in. Buy a fresh maternity bra after giving birth for the truest fit, and expect to need a few sizes along the way.
A nursing bra should fit snugly without feeling tight, supporting you without poking your skin or restricting your movement. Your breasts should fill the cups with no spilling over or gaping. Because your size shifts throughout pregnancy and nursing, re-check your fit regularly.
Run through these fit checkpoints each time you try one on:
Thirdlove offers three core nursing bra styles: a wired 24/7® Classic, a seamless wireless Form, and the wireless Kindred Bravely Signature Sublime Contour. That gives you an underwire nursing bra for lift, plus wireless and seamless options for softer, all-day wear. Each one adds drop-down access that a regular everyday bra does not, and you can browse the full range in our bra styles.
This wired maternity bra is modeled after our best-selling 24/7® Classic T-Shirt Bra, built to support and comfort in equal measure. It features no-slip pleated straps, a scratch-free tagless label, a soft foam back closure, and memory foam cups with a smooth drop-down. Adjustable straps and five hook-and-eye closures keep the fit secure as you feed, pump, and change size, in 32-44 bands and A-H full cups.
Want everything you love about a classic nursing bra without the underwire? Our Form Seamless Nursing Bra gives you that freedom with full coverage. The nylon and spandex blend delivers 4-way stretch that supports every movement.
Soft memory foam pads are removable for a custom fit, and the seamless finish stays silky on tender skin, in inclusive XS-3X sizing.
Looking for a supportive nursing bra that is comfortable and stylish? Our Kindred Bravely Signature Sublime Contour Nursing & Maternity Bra is our top wireless nursing bra pick. It features molded cups, a stretchy wireless construction that holds you in place, and nursing clips for convenient feeding. A low-cut neckline and ballet-style back keep you looking beautiful under almost anything you wear.
Yes, Thirdlove makes supportive nursing bras for larger busts, with bands from 32 to 44 and full cups from A to H. If you need nursing bras for large breasts, the wired 24/7® Classic adds underwire lift and pleated straps that spread the weight. For plus size nursing bras with softer support, the wireless Form Seamless style reaches XS-3X with 4-way stretch.
Yes, Thirdlove nursing bras work for pumping, since the drop-down cups and nursing clips open for one-handed access. A nursing and pumping bra needs to stay put and free your hands, and our secure closures and adjustable straps do both. Fold or clip the cup down, position your flanges, and keep the band supportive while you pump.
For non-feeding moments, our wireless bras give you the same easy coverage all day.
Thirdlove nursing bras come in band sizes 32 to 44 with A to H cups, plus wireless styles in XS to 3X. Our Precise Size™ feature helps you land the right fit when your body feels especially tender and sensitive. Not sure where to start?

Do You Really Need a Nursing Bra?
Not strictly, but most moms find one worth it. You can nurse in a regular bra, though tugging cups aside gets awkward fast and can dig in as your size shifts. A nursing bra's drop-down access lets you feed one-handed without undressing, which is the whole point during those middle-of-the-night sessions.
How Many Nursing Bras Do You Need?
Two to three is the practical sweet spot for most moms. That gives you one to wear, one in the wash, and a spare for leaks or spit-up, so you're never caught short. If you pump or nurse around the clock, keeping a bundle on hand means less laundry pressure.
Can You Sleep in a Nursing Bra?
Yes, and a lot of moms do for extra support and leak coverage overnight. Reach for a wireless, soft style like the Form Seamless, which has no hardware to press in while you're lying down. Skip anything tight or rigid at night, since gentle, breathable support is what keeps you comfortable through interrupted sleep.
Can You Wear an Underwire Bra While Breastfeeding?
Yes, as long as the fit is right for your changing shape. Thirdlove's 24/7® Classic Nursing Bra uses a flexible, poke-free underwire that supports without pressing on milk ducts. Since your band and cup size can shift during nursing, getting measurements right matters, and the Fitting Room Quiz is a good starting point.
Are Thirdlove Nursing Bras Good for Sensitive Skin?
Yes, several styles are made with sensitive skin in mind. Our seamless Form Nursing Bra uses a silky, tag-free nylon and spandex knit that stays gentle on tender skin, and our breathable cotton nursing bras keep things naturally soft. If you're dealing with dryness or chafing while nursing, a soft cotton or seamless style keeps things cool and irritation-free through the day.
