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 said this nursing bra 'looks amazing' and 'fits perfectly.' The plunge style delivers both functionality for nursing and an attractive appearance. With a 5-star rating, shoppers appreciated the combination of fit and aesthetics in this supportive garment.
- Looks amazing, fits perfectly
I am actually OBSESSED with the Hotmilk Plunge Nursing Bra in Mocha! Finally a nursing bra that is sexy, fitted and still actually supportive!! The lace is so pretty and flattering and doesn’t give that ugly bulky nursing bra look at all.
And the magnetic clips!!! Literally life changing.. once you use magnetic clips you honestly can’t go back.
I was also shocked at the sizing because the fit check put me at a 16F and I thought there was no way… but it fits PERFECTLY. No overhang, no bulging, nothing spilling out, just the nicest fit ever. I genuinely wear mine everyday.
Only negative is the stock 😭 I want this bra in every colour but got told more colours in my size won’t be available until September which is SO far away and I do not want to wait that long 🥹
This has been my favorite nursing bra since my baby was born! It's equal parts ****, comfortable & practical. My new go-to!
Thank you for your review Leslie, you look amazing in Heroine Plunge!! xx
I bought this bra to wear for an upcoming wedding where I am Maid of Honour! I need to feel my best on the day but also have comfortable support and easy access for feeding my babe. This bra is so perfect - the lace is so pretty and I love the rose gold clips. Well done Hot Milk 👌
Thank you for your review Rose, it is such an honour that you have chosen a Hotmilk bra to wear while you are Maid of Honour!! xx
You can undo the magnetic clips with 1 hand by sort of folding half of it forward. It took me a while to get the hang of it. I'd suggest trying it out a few times when not about to feed a crying baby. :)
Lovely bra. Fits me where full cups don't because I'm more bottom heavy breast wise. Ie most of the breast is lower down, below the nipple.
The 2 straps I think look unusual and cool. Were fine once I'd adjusted them.
This is the ultimate bra. I am not even nursing anymore and I still bought another one. No other brand caters to ladies with bigger tatas like Hotmilk. I just wish they would make the Heroine Plunge part of the Evolve range too! I need to order more! Normally an 18D but the 16DD fits like a glove!
Baby is due very shortly and I'm struggling to find a comfy bra let alone something vaguely attractive and also easy feeding friendly. This bra ticks all the boxes. So comfy, good support and also the magnetic clips are perfect! Plus it looks incredibly pretty for a nursing bra!
Thank you for your lovely feedback on Heroine Plunge! Best wishes for the arrival of your baby xx
Looks amazing, fits perfectly
Hi Akansha, we're thrilled to hear you love the Heroine Plunge Nursing Bra! Thanks for your wonderful feedback. xx
I am 1 year postpartum and am a 32 G. I have always found it difficult to find supportive flattering bras but found it especially difficult to find that in a nursing bra. This is my new daily bra. It separates and lifts and makes me feel like I am wearing a normal bra! I am still able to tuck my hands free pumps on the bra which is great for work. I feel so much more confident in my clothes again!
Thank you for your lovely review Mary xx
Its comfortable as well as flattering, makes you feel supported and feminine. Something that makes you feel sexy again postpartum
Thank you for your review Claudia, it is so lovely to hear that you are happy with your Heroine Plunge xx
Very comfortable and looks stunning! Easy to nurse in
Thank you for your review Gem! xx
It has been so difficult to find a maternity bra that was comfortable and didn't make me feel frumpy. The colour is so pretty (so sick of black and beige being the only options) and it is comfy enough to wear all day without thinking about it. So happy!
Thank you for your review Ash, so pleased to hear that you are happy with your Heroine Plunge xx
This bra, this is the unicorn of bras for the tear drop boobies! This is for the girls quite heavy in the bottom and empty uptop. I have loved every Hotmilk bra I have owned, but when I tried this one on this afternoon, I said wow! I was gobbsmacked. I looked so beautiful in the Heroine Plunge. The support in the lower part of the cup lifts and fills the upper part of the breast giving you that feel that gravity has not yet taken hold of you, and you are firm and shaped. She passed the bend test with flying colours. There was no falling out, no migrating to the middle. The magnetic clasps on this bra are so easy to use, no fiddling with a snap clip wondering if it's done up or not- the magnet pulls it straight back in place. You can not tell this is a breast feeding bra on looking at it, so it's perfect for non nursing wear as well.
**Full disclaimer, I am no longer a nursing mum, I've come back to hotmilk after 5 years as they released the evolve range and I truly missed the hotmilk support! I am big busted (14G) and I know how frustrating it is to buy a bra that actually holds you in, gives abit of lift and lets you feel pretty. No one makes bras for voluptuous breasts like hotmilk. While I love the evolve range, the colours are currently limited to two and I wanted a pop of colour
Thank you for leaving us a lovely review on Heroine Plunge Amy! This is such a lovely style and surprisingly supportive for a fully lace bra! We will be expanding the Evolve range in the near future so keep an eye out xx
Such a pretty and comfortable bra. Finally feels like I'm wearing something that looks good and that I can feed in. So great, I bought two!
Thank you for your review Naomi, it is great to hear that you are loving your Heroine Plunge bras!! x
I love this bra. I love the fact that it looks pretty and like a "normal" bra rather than a frumpy boring nursing bra. I love that it's so comfy, it doesn't dig it, it fits beautifully and is supportive. But most of all I will always choose a magnetic closure now. I cannot go back. I can actually feed my son and close my bra without having to put him down to scrabble around and close the bra
Thank you for leaving us such a lovely review Katie! It is so amazing to hear that you love your Heroine plunge bra (it is also my fave!!) xx
This is a beautiful bra. I would personally feel more comfortable going up a cup size, due to the plunge style. I feel like I'm spilling out the front a little. Or maybe the style just isn't that practical for a G cup.
Similarly, the two thin shoulder straps, while pretty, aren't ideal for very large breasts. I'm more comfortable with thicker straps. I'll still wear it, but likely just for short periods with certain outfits.
Thank you for your honest review Felicity, we would usually advise to go up a size if you find you are spilling out of the front. Plunge styles do tend to make a bigger bust more prominant in the middle, if you don't love that look I usually try scoop my breasts into the cup more to lessen the cleavage. I do hope you get some use out of your Heroine Plunge, it is such a beautiful bra! If you ever need any fit help we are always available via email to help out x
Honestly love this bra, not just the prettiest nursing one I own but one of the prettiest I own full stop. The magnetic catches can be a little tricky to unfasten one handed as they are so strong but it makes fastening after a feed a dream.
Thank you for your review Lucy, it is great to hear that you are loving your Heroine Plunge bra! Here is a video to help you with the magnetic clasps - https://vimeo.com/872747939
So comfy & fits perfect
Thank you for your lovely review Elizabeth! x
Love this.
Starting wearing these already as they give such great support and shape. I had to change the size but the customer service was so speedy it took no time at all.
Hi Bethany, finding the perfect fit may mean making some changes, so we really appreciate you highlighting our speedy customer service to help other mamas find their ideal size x
This was my first purchase from Hot milk and I wouldn’t buy from anywhere else. I wasn’t sure of my size but I followed the online guide and ordered three bras with the idea to keep my favourite two and return one with free returns. I will definitely be buying all my bras here in the future, you can’t get this quality in store anywhere.
Thank you Miranda for the amazing 5-star review! We're honored to be your go-to source for nursing bras and look forward to continuing to provide you with the exceptional quality and service you deserve.
The fit was really good, true to size. It is soft and comfortable but also not grumpy or unattractive. I really like it and glad I purchased
We love the twin strap detailing and discrete magnetic nursing clips x
I'm in my third trimester and a 32H / 32I, and this bra has honestly made me feel like myself again. I thought I couldn't do underwires while pregnant, but the flexiwire is really comfortable to wear all day. Highly recommend!!
Best bra during my pregnancy!
Feels so great to to have a pretty nursing bra to make me feel special. Love it - beautiful and comfy and functional.
I went from feeling like a grandma to feeling like me again! A bra that gives larger boobs great support and look amazing!
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.
