This is the best bra I’ve owned since wearing your nursing bras! It’s so comfortable don’t even know it’s on. Fits like a glove. Nice soft and pretty too. Will be buying more!!!
Thank you for your lovely review on Refined, Lisa! It looks amazing on you xx
I have been searching for a supportive bra that gave great shape, was comfortable and looked good. I haven’t been able to wear underwires for a few years and have had some breast cysts along with rib pain, so wore non wired and I can’t tell you how many I tried, sent back, or lost their shape super quickly.
I had given up and resigned to hoisting my sometimes sore big boobs into ones that I just didn’t like, until I saw the advert for the evolve range. I thought about it for a while and was reluctant to buy yet another one that would end up returned, and at £45 not the cheapest bra around. But, wow I love this bra! It does everything that the description says, and really is very comfy too. It feels supportive, soft against the skin and the flexi wire is a total game changer, especially for anyone like me who has had to ditch underwires for boob issues. Plus it doesn’t compromise on style - it’s pretty, stylish and pretty sexy compared to my old plain non wired ones.
Well worth every penny and I will be ordering more.
I’d recommend this to anyone but especially perimenopausal women who can’t compromise on comfort but who what to feel fabulous at this moment in your life.
Thank you for your wonderful review Karen!! I am so sorry to hear that you have had such struggles in the past with bras but I am so glad that you found Refined, it is such a game changer xx
Yes I've found it! Looks great, feels great ALL day.
I was a bit reluctant buying on line but my size was the perfect match. Last wore Hotmilk 19 years ago with my first born. Comfort around my sides/ribs and nice cup shape. I will be buying more! Thanks
Thank you for your review Hayley, so pleased to hear that you love your Refined bra! x
Love the bra construction.
Smooth, non scratchy band. Four hook positions, strap adjuster slides at the front (omg how sensible is that!). Bought 10E, a tad small in the cup but I wasn’t going to send it back. Got another in 10F and it’s perfect. F cup upward have wider straps. I think wider straps should be offered below F cup too.
Thank you for your review Lynne x
Like a warm hug! I have such bad luck with bras (12G-12J) so it's like a one in a million chance that one fits, not only was this perfect but it's like someone hugged me and said 'there ya go, you deserve this!'. The fabric is so soft, no scratchy bits, it feels almost like it's wireless it's just so smooth. Heaps of hooks on the back too, I often find bands too wide or too small. I also love that this doesn't pull my **** into my armpits whilst also preventing uniboob! Would love it in white 🤍 Thank you!
Thank you for your lovely review on Refined, Sarah! I am so pleased to hear that you love it x
I am one year postpartum with my 2nd baby and have just finished my breastfeeding journey. Ive been a huge fan of the hotmilk nursing bras for the past 3.5 years so thought I would give this bra a go - I am SO glad I did! Definitely the comfiest (non nursing) bra I’ve owned and makes my **** look a bit perkier which is a nice bonus haha. 10/10 would recommend
Hi Kirsty,
Thank you for leaving us such a lovely review on Refined! We are also so glad that you took a chance and gave it a go, it is such a lovely bra xx
Common Questions about Refined Flexiwire Bra
Everything you need to know about Flexiwire fit, and finding your size
Start with your current measurements or a bra that currently fits.
Refined is designed with a fuller cup shape — if you're not as full on top, size down a cup
If you have softer underarm or back skin, consider sister sizing — up a band, down a cup to ensure nothing digs in
Contact our fit team for help with your size. Don't forget to take our Fit quiz.
Yes — Refined uses the same Flexiwire technology from our nursing range: a flexible low-gauge wire that bends with your body rather than sitting in a fixed position. It's significantly more comfortable against post-nursing tissue than standard rigid underwire. The underarm smoothing panel also ensures no digging where tissue is soft or sensitive.
For most everyday tops, yes. The lace sits on the upper cup, while the lower cup — the part against the fitted line of your top — is smooth microfibre designed to lie flat.
Under very fine or sheer fabrics, you may see a subtle hint of the lace edge. If full invisibility is what you need, Effortless Sculpt is our completely seamless option.
We offer 30-day returns on unworn bras with tags attached. We also have Refunds or store credit available.
