Why we built Obsession
- Larger E–J busts with no T-shirt bra that gives a smooth finish under clothes
- Returning to work with nothing that holds its shape all day at E cup and above
- Underwire that digs into a fuller bust before lunchtime
- Standard bras scaled up — not actually built for larger cups
- Engineered T-Shirt for larger busts A T-shirt bra specifically built for E–J cup
- Spacer foam cups smooth and contour under anything you wear, all day, without losing shape
- Flexiwire Adaptability lifts and supports a fuller bust, moving with your changing shape without digging
- Wider band and straps Wider 4-row closure and wider 18–22mm straps on larger sizes: the structural details that make the real difference at E+ cup

Customers praised this nursing bra as "THE bra" for larger busts, offering excellent support and a flattering shape. One shopper noted it's "super supportive, comfortable" with inclusive cup sizes. The flexi wire provides support without discomfort. Some found the lace slightly itchy initially, and clips may occasionally come undone. Highly recommended for fuller busts.
- Super supportive, comfortable and cup sizes are so inclusive
- This is the only one I have ever felt even moderately confident wearing at work
- The flexi wire does an amazing job!
OBSESSED. This is your PSA announcement for all my busy babes out there struggling to breast feed your bubs with bras that don’t support you. Put your sports bras aside and do yourself a favour and purchase one of these wire nursing bras. Super supportive, comfortable and cup sizes are so inclusive, you can thank me later 😊❤️
Fits very well and is more supportive for larger busts than other nursing bras
Thank you for your review on Obsession xx
I am 7 months postpartum and I truly believe I have tried every single nursing bra in my size on the market. This is the only one I have ever felt even moderately confident wearing at work. Great shape, no sagging, no weird bulges, nothing digging in painfully to distract me from getting stuff done — just totally functional. I can pump in it easily (I use it with one those hands-free pumping bra false front adapters from Bravado and it works great). I wish the lace around the front under the cups was ever so slightly softer (in certain positions it is slightly itchy), but it doesn’t bother me nearly as much as other ones I’ve tried and is definitely not a dealbreaker. I am buying a second one now.
Thank you for such a wonderful review Jess! I am so happy to hear that you love your Obsession Contour T-Shirt bra and that it's working so well for you both at work and for pumping. xx
The only nursing bra I've found with good support, and a nice shape, for a bigger bust. I'm a 12GG and I LOVE this bra.
Hi Leah, it is so lovely to hear you're loving your Obsession Contour T-Shirt Nursing Bra! xx
Love that I can still get support and a contoured bra for a large bust that is also suitable for breastfeeding!
Thank you for your review Natalie, it is great to hear that you are loving your Obsession bra!! x
Straight off the bat the quality and material are great so far, Fit nicely, good support. I am disappointed that the “Capital A” under the clasps for extra support whilst feeding if I’m honest feel pretty much useless for me (40GG) it may just be die to my size but I was really hoping this would be the biggest game changer for feeding my little one when she’s born but it looks as though I’ll still need to hold them up in some way depending on feeding postions.
All in all thought I’m looking forward to using them and seeing how they compare in the long run.
Hi Hannah, We're delighted you find the quality and fit supportive overall. As for the A-frame sling, some larger cup sizes may find it quite enough for full support while nursing. Our design team is exploring additional reinforcement options for future styles. For now, we suggest using your hands or a nursing pillow to help lift and position baby comfortably during feedings.
So comfy that can wear it all day everyday! Gives a great shape and support, with no digging in! It’s nice to have a practical and pretty bra to wear in a size F, that can also accommodate growth and feeding when the time comes!!
Thank you Sheryn for the fantastic 5-star review! We're thrilled to hear you're loving the beautiful comfort and support of Obsession Nursing bra. It's so important for new mamas to feel confident and supported during this precious time x
Fits well and seems comfortable.
I wish there was a wider selection for bigger busts through.
This is super comfortable and feels like I'm not wearing a bra. This is third baby and my first Asling bra, I'm used to a side sling, but I don't think that will be a problem. As a 36M (36L pre pregnancy) it's very hard to find a good, comfortable, supportive bra. I am happy with my purchase
Shopping for bras when fuller busted is hard enough without the added necessity of nursing. Hotmilk have hands down the best and largest range to cater for just that! Great quality and value as well. I also love the look of these too!
I'm a 12H and struggle to find anything that fits and makes me feel nice too. I exclusively express using wearables and they also fit perfectly in this bra!
I love this bra, I wear it daily. My favorite nursing bra so far, I am 6months and counting nursing and this is so supportive which helps me nurse my son more “hands free”. I should probably get another one soon!
Super comfy and supportive- I was struggling to find something that can properly hold up my boobs without an underwire but the flexi wire does an amazing job!
This one is my absolute favourite. It’s so comfortable and flattering. I’ll definitely be buying more of these.
As a 36J, the thought of a traditional non-wired nursing bra filled me with dread because I NEED wires for the support. So glad I found Hotmilk and this bra. I have 5 of this style in different colours that I have worn on rotation since giving birth 8 months ago. It’s supportive, great coverage and feels secure yet comfortable. My only gripe is the clips can sometimes come undone if I bend or stretch too much. And the lace on the underwire is itchy on the first few wears. Other than that, it’s genius. Please please do more colours!
Absolutely cannot go on enough about how amazing these bras are, there’s very few bras that can handle my boobs generally so it’s been really hard finding a good maternity bra. This style takes the cake I LOVE it it has great support is comfortable and quite attractive (no granny bras around here).
Excellent bra with great support for larger bust, fits perfectly and gives a natural shape, made from soft material.
Flattering and attractive, as many other brands have very unattractive bras for large busts, this one is lovely.
This bra is so comfy and supportive, they are definitely my favorite I even wear them when not breastfeeding they are so comfy and supportive.
I really wanted to love this bra, but ended up returning it as it just wasn't comfy for me. I had the size correct (had already exchanged once) but it still wasn't sitting correctly. I found the moulded cups awkward and the lace panels a bit rough.
Hi Rhylee, like a great pair of jeans not every style will suit every mama's shape, style or comfort needs. Please reach out to support@hmcollective.com for other style suggestions x
I love the obsession bras, I have a couple. These fit my body so well and my only regret is that its taken me until my third baby to find the perfect nursing bra!
This is everything I want in a nursing bra. The flexi wire makes me feel supported, the cups are smooth and soft, and the extra long fastener at the back means they fit comfortably through changes to my shape. I previously owned this bra for 2 years of feeding and bought another because my cup size has changed. I wouldn't bother with anything else, but decided to try one other hotmilk flexi wire bra while I was at it, which came in the wrong colour. Hotmilk sent me the correct colour immediately and allowed me to keep the one they had sent me by mistake- WHAT AMAZING SERVICE!! Now I own 3 new feeding bras that will see me through to the end of my breastfeeding days in comfort and style!
I struggled to find a comfortable bra that fit my growing pregnancy bust. As soon as I tried this on, I almost cried it was so comfortable and I didn’t realise how much my other maternity bras had not been supporting me properly. Couldn’t recommend this bra enough! It is very comfortable with straps that are slightly wider, so don’t dig in. Each cup is separated nicely to avoid any rubbing together. I’ll definitely be purchasing another one!
Zoe, this is exactly why we do what we do. So glad you have found your perfect comfort and support x
Good quality, fast shipping

Obsession 2.0 is engineered specifically for E–J cups — not a scaled-up version of a smaller style. Key design differences at E+ cup:
- Spacer foam cup depth matched to fuller bust proportions
- 4-row hook closure (wider than standard 3-row) for added band support

- Improved A-frame for larger cup access
Yes — Flexiwire moves with your bust, rigid underwire doesn't. The Australian Breastfeeding Association notes flexible-wire maternity bras are "less likely to cause problems." The A-frame clip releases fully during feeds, removing any pressure on breast tissue.
