Customers praised this nursing bra as "super comfortable" with excellent support for larger busts. Many said it "fits so well" and accommodates fluctuating cup sizes during pregnancy and breastfeeding. However, some noted sizing runs small in cups and straps can be rough-edged. Shoppers loved the soft fabric, easy nursing access, and flexibility.
- I don't think I have ever been this comfortable in a bra before. I'm never going back.
- So comfortable. An absolute must for mamas. Had to order another.
- Finally found one that I don't fall out of when I bend over. In love with this bra.
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 Questions about My Necessity Bra
Everything you need to know about seamless FlexFit sizing, Regular vs Busty fit, and hospital bag use
The Necessity is sized S–XXL, so start with your usual clothing size for the band. For the cup, choose from two options: Regular (A–DD) or Busty (DDD–I). Select your current cup size — the fabric stretches 2–3 cup sizes to accommodate your changing shape as your milk comes in. If you're between sizes, we recommend sizing up.
Yes — it's one of our top hospital bag recommendations. Here's why:
- Seamless construction — no pressure points from day one
- FlexFit sizing removes the guesswork of your exact postpartum size
- Side-sling clip is intuitive even in the first days
Soft enough to wear overnight from the first night in hospital
Yes — My Necessity is our most-recommended sleep style:
- Seamless, no pressure points overnight
- Wirefree throughout
- 6-hook closure can be fastened loosely for overnight comfort
- Available in Regular (A–DD) and Busty (DDD-G)
- Regular — A–DD cup, standard cup depth
- Busty — DDD-G cup, extra internal support panel for a fuller bust
Both use the same seamless FlexFit recycled nylon — choose based on your cup range. Still unsure? Chat with our fit team
My Necessity is pretty forgiving so we get far less returns on this style due to how adaptable it is. Choose your regular size.
Between sizes? Size up for comfort and room for a breast pad
6-hook closure extends +8cm for postpartum adjustment

Yes — FlexFit's stretch fabric flexes around most wearable and hands-free pumps, so you can pump without changing bras. For dedicated all-day pumping support, our Freedom Pump Bra is purpose-built for it.
