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 for its underwire support, saying they "actually feel like I have boobs again!" The bra offers excellent quality and fit with "incomparable" ease for breastfeeding. Some noted the clip is initially stiff but loosens with wear. Concerns about wire durability with repeated use.
- So grateful that a breastfeeding bra has been made with an underwire!
- Amazing quality and fits like a glove.
- The ease it gives me when breastfeeding is incomparable.
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 😊❤️
Amazing fit for bigger busts ! Great shape.
So pleased to hear that you are happy with Obsession 2.0! x
Lovely bra, lots of support but comfortable
Great bras really comfy. I needed to return one and the process was easy. These are my fav nursing bras
Finally a bra that fits and makes me feel put together again. Lightweight and flexible with great support.
Thank you for your review Amy, so pleased to hear that you love Obsession x
Fits very well and is more supportive for larger busts than other nursing bras
Thank you for your review on Obsession xx
Finally a comfy maternity bra!!
So good and actually gives me the support I need.
Thank you for your lovely review Olivia xx
This was so uncomfortable. Will be returning.
Bought a second one of these in another colour for my second bub. Super comfy and easy to unclip. I'm a 10H so love that this actually fits too!
So pleased to hear that you love Obsession, Emily! xx
So grateful that a breastfeeding bra has been made with an underwire, I actually feel like I have boobs again! They’re so comfortable too.
Only thing I’d say is the clip is a little tough to begin with but seems to be getting better with more wear.
And I’m hoping that the wire doesn’t pop out like some of my ordinary bras in the past with the constant opening and closing for feeding.
Thanks for your lovely review Jaz! x
Love the wide range of adjustability in the bra.
Thank you for your lovely review x
Amazing amazing quality and fits like a glove. I feel fully supported when wearing these bras and the ease it gives me when breastfeeding is incomparable.
Thank you for your amazing review on Obsession! xx
So fast and efficient with delivery!
Easy to liaise for exchange in size!
Overall 10/10.
Thank you for your review Olivia, it is great to hear that you had a 10/10 experience with us! xx
I was a little cautious about buying a bra online but I am so glad I took the chance. This bra offers excellent support and is a great shape, I will be buying again in black! As a larger bust lady, I found the non-wire breastfeeding bras so lacking in support and felt the shape was awful and unflattering. I recommend this bra if you are having the same issues!
Thank you for your lovely review, it is so great to hear that you are loving your Obsession bra! x
Provides great under wire support whilst allowing you to nurse. Clasps are great and bra is very comfortable. Would recommend and will buy again in another colour.
Thank you for leaving us a lovely review Claire, I am so pleased to hear that you are loving your Obsession bra! x
Very comfortable bra, fits large chest (I'm a size H), in between my two kids when I wasn't feeding I still wore these bras as my go to.
Nice fit, but has lace so you feel good in it
I am so glad to hear that you are loving your Obsession! x
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
These are essential for nursing and comfortable. Was able to exchange my size easily.
Thank you for your lovely review Charlotte! x
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
I couldn’t give this bra enough stars! It’s the ONLY wired bra with cups that I’ve been able to find in my size. The support is perfect. The cups are a little stiff to fold down to nurse at first but I got used to that pretty quick and just give them an extra firm tug when pulling down to nurse.
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 fabulous 5-star review! It's such a great feeling finding the perfect fit that allows you to feel confident and supported every day - especially during this precious time x

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
The best nursing bra I’ve tried although sometimes tricky to get the boob out, I feel like the cup could fold down lower! Very easy to undo and fasten back up with one hand!
Hi Teresa, we're so glad you love this style! x
I have never tried this bra before and it is so comfortable and supportive. The straps are easy to get down for breastfeeding unlike other brands. I will definitely be purchasing this in another colour!
Finally a comfy one! Fits well, easy to wear. Quite high cut

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
- Wider straps: 18mm standard, 22mm on the largest sizes (32HH/34H/36GG+)
- Double-layered band for extra smoothing
- 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.
We offer 30-day returns on unworn bras with tags attached. We also have Refunds or store credit available.
