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
Customers praised this nursing bra for exceptional comfort and support, with one noting it "actually holds your boobs up" unlike many alternatives. The soft, stretchy fabric is ideal for postpartum and nursing at home. Some mentioned it doesn't provide the most flattering shape for wearing outside.
- So comfortable and actually hold your boobs up. Proper support. 10/10
- Great for immediate postpartum and nursing. Very comfortable.
Super comfortable bra with great adjustable sizing (which helps with my size changing through pregnancy) - now my favourite bra
Thank you for leaving us a review on My Necessity, so glad to hear that you love it! xx
Love this maternity bra! It is soft, comfortable, and supportive, with much better quality than the cheaper options I tried before. I wear it both during the day and at night, and it stays comfortable the whole time. Definitely worth the investment.
Hi Naira, we're thrilled to hear you love the My Necessity 2.0 FlexFit Nursing Bra! Comfort and support are what we aim for. Thank you for sharing your experience! xx
Very comfy, I forget I am wearing it. Bought a black and a skin colour one to try them out, I will be getting more of these.
First pregnancy, no real idea what I am doing, but I am really happy that I re-took my measurements and then kinda guess-timated from there a little extra for when my milk comes in after bub arrives! At first I thought I ordered a size too large but then tried it on and oh! my goodness! It was perfect on the smallest setting, with room to grow if/when needed. Great material, very soft. I usually go for a M or L with bras, but this time decided to take my chances with the XL size. Best decision ever, and so very worth it.
Thank you for your lovely review Sarah xx
This bra is super comfy. I’m currently 24 weeks pregnant and find I will have room to grow. I sized up as per the size chart but could probably have stayed an M. The size L is still good though, especially for sleeping, and I will be purchasing some more
Thank you for your lovely review on My Necessity xx
I was pleasantly surprised to feel the comfort and equally the supoort offered by this staple
You look amazing in your My Necessity Molly! x
Very comfortable and easy to breastfeed.
I regret not buying these bras soone! I breastfed for 6 months in cheap nursing bras that had no padding and gave me a terrible shape under clothing - they made me feel gross. These bras are so comfortable and supportive and SO easy to unclip/clip discreetly with one hand. Would recommend to anyone I know that is breastfeeding
Thank you for your review Laura, so glad to hear that you are loving My Necessity x
3 days post partum and my milk is in - boobs like rock melons and with the gravitational pull of planets! But the recommended size has been perfect and it’s the first nursing bra that’s actually comfortable and doesn’t make me feel dowdy, despite spending a fortune last time with different brands. Have both the flexi fit and the forever new but adoring the forever new in particular. About to order some more!
These bras are incredibly comfortable and functional, I have bought them in multiple colours
So pleased to hear that you love My Necessity Emma! x
Highly recommended by lots of mums, I wasn't sure. But OMG - this bra is incredible. It's so comfy, holds your boobs nicely, fits well and altogether just the best bra I have ever worn! Can't wait to get more.
Thank you for your lovely feedback Lucy xx
This is my 3rd pregnancy and I honestly wish I'd discovered these way earlier. Such good quality and support. Highly recommend
I bought 3 bras from Hotmilk and loved them all. As someone who was a G cup before I got pregnant I was finding it so difficult to find a bra which could accommodate my new size. These are great quality, supportive and the clasp is super easy to use once you get the knack. So worth the money!

Fits beautifully and very soft but supportive
Fantastic feeding bra & super comfy! Came back and bought more!
Hi Jenny, we're so happy to hear you love the bra! Thanks for your support and for coming back to us. xx
Unbelievably soft!!! Some other brands are scratchy fabric and really uncomfortable, I can’t get over how lightweight but supportive this feels. It is so soft on your skin you can absolutely justify the price, I will be getting more once bub is here in a few short weeks!
Thank you for your lovely review Kim! Best wishes for the arrival of your baby xx
I love that it’s got me through multiple stages of pregnancy. It’s super comfortable, supportive and flexible.
Thank you for your lovely review Nicole xx
I bought this as I finally reached the stage in pregnancy where none of my old bras fit. I tried 3 other pregnancy/nursing bras before this and found them baggy and unsupportive. This bra is great. Really comfortable, but still supportive and gives a nice shape under clothes. Loads of stretch and hook options so I’m hoping it will fit all the way through. The nursing clips seem very easy to use. I would definitely recommend.
Thank you for your review Ellie, it is great to hear that you are loving My Necessity x
Im in 3rd trimester and this bra is so soft and comfortable!
Highly recommend
Thank you for leaving us a lovely review on My Necessity, Kristine xx
Soft and comfy and reasonable support for large breasts
Supportive and comfortable. Good quality with soft fabric. Ease to clip and unclip for feeding.
Thank you for leaving us a lovely review on My Necessity! So pleased to hear that you love it x
Bought these while pregnant with my second baby and found this really supportive and growing with my changing body. I will be buying at least 5 more of these! Throwing out all my old nursing bras!
Thank you for leaving such a lovely review on My Necessity! xx
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 with 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.
