The Nursing Bra That Doesn't Look Like One
- No real support for DD+ and large bust sizes
- Maternity and Nursing bras that look and feel like medical equipment
- Forced to choose between comfort and confidence
- A bra that fits today but not by next month
- Flexiwire styles that don't dig. Wire-free styles that don't collapse. Both built to actually support you.
- Real lace, real nursing lingerie — you'll forget you're wearing a nursing bra
- Cotton-lined cups keep you cool, dry, and comfortable through every feed
- One bra, every stage — six back hooks adjust as your body changes from pregnancy through postpartum

Common Nursing Bra questions
We say as soon as you feel your bust is changing. This varies greatly for everybody, but you'll notice a change in how your bra is fitting and you don't want any digging in. Buy 2–3 to start — your size may shift slightly once your milk comes in. If you experience significant growth earlier in pregnancy, a soft wire-free maternity bra can bridge the gap like our My Necessity bras.
Yes — you can wear our flexiwire technology, athough we like to say not to wear them for the weeks around when you give birth and are most sensitive. At this time you don't want anything pressing on milk ducts, which can contribute to blockages. Most lactation experts suggest avoiding rigid underwire in the first 6 weeks while your supply is establishing. After that, a well-fitted flexiwire or soft underwire nursing bra is safe for most women. Try Temptation.
We have a fit quiz here to help you wtih this. Or contact us for help with your size. During pregnancy, we recommend to roughly go up one cup and one back size from your pre-pregnancy bra as a place to start. Often you'll get fuller again in the bust when the milk comes in at birth. Then at around 3 months they'll settle again.
A nursing bra makes breastfeeding significantly easier. Regular bras don't accommodate the daily size fluctuations as your breasts fill and empty, and accessing them for feeding is awkward — especially one-handed with a hungry baby. A nursing bra with a drop-down clip lets you feed quickly and comfortably without fully undressing.
We recommend at least 3 nursing bras — one to wear, one to wash, one spare. In the early weeks when leaking is common, a fourth is useful. Start with 2–3 before your baby arrives, then add more once your size has settled around 6–8 weeks postpartum.
Yes, you have enough costs to worry about! A nursing bra with multiple hook-and-eye settings and adjustable straps can accommodate your changing size throughout pregnancy and carry you through into breastfeeding — so you don't need to buy separate maternity and nursing bras.

Born from a founder who refused to settle
Twenty years ago, Lisa Ebbing refused to wear nursing bras that made her feel invisible, just because she was becoming a mother. That refusal sparked a revolution. Today, Hotmilk has sold over 2.5 million maternity and nursing bras and briefs worldwide.
