Measure Your Under Bust
Measure Your Full Bust
Wearing an unpadded bra, wrap a measuring tape around the top of your ribcage. You’re looking for a snug fit - so we recommend tightening on the exhale and noting the smallest measurement to the decimal.
Wrap the measuring tape around the fullest part of your chest, making sure the measuring tape is paralell to the floor. Relax your shoulders and measure where it falls.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 1 month ago
Customers say this wireless bra is extremely comfortable and supportive, providing excellent coverage without underwire. Many find it shapes and smooths effectively, preventing spillage and creating a natural silhouette. The mesh panels help control bulges around the sides and back. Users appreciate the soft, breathable fabric and all-day wearability. Common feedback includes that it runs small, with many needing to size up from their usual measurements. Some mention initial stiffness that softens after washing. While most praise the fit and support, a few note issues with strap slipping or tightness under arms. Many customers become repeat purchasers, calling it their new favorite bra.

For anyone that has trouble finding a comfortable bra, this is the one for you. Finally found one that I'm not constantly pulling up a slipping strap and can almost forget I'm wearing one.

Hilary B.Verified BuyerReviewingShape & Smooth Bra - Rated 3 out of 5 starsYesterdayNot perfect fit
I bought the same size as my revolution bra, but this one is tight and instead of being smoothing in the back, I does the opposite.
They all fit different
pia w.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 stars2 days agoFinally a bra that fits properly!
I am so pleased with the overall fit of this bra! I have an awful time getting one to fit properly. I am so pleased I will be ordering more.

This bra has great support, almost as good as the catalyst bra. I have a generous bust and this holds me in and keeps movement to a minimum. Nice invisible look under clothes to!

Cheri H.Verified BuyerReviewingShape & Smooth Bra - Rated 2 out of 5 stars2 days agoOkay but I didn’t feel it was too smooth!
This bra is made very well but I found it too restrictive for my lifestyle. I prefer a softer more relaxed fit.
Charlette L.Verified BuyerReviewingShape & Smooth Bra - Rated 4 out of 5 stars2 days agoBra
This would be a whole lot more comfortable with wider straps..
The straps dig in.
Darcy R.Verified BuyerReviewingShape & Smooth Bra - Rated 4 out of 5 stars3 days agoBeautiful comfortable bra
I gave it 4 stars because I had to return it for a smaller size. I seem to be the only one in the reviews I have read so far that had to return it because my normal sizing didn't fit properly. I found the cup sizing a bit big on me. When I took it out of the packaging I remember saying to my boyfriend there's no way my boobs will fit properly in this bras. It looks so big and I was right. For any woman that has deflated boobs from breastfeeding I would recommend sizing down for this style bra. I ordered a large because normally a B36. I did return it for a medium. Other than the sizing problem for myself it's a beautiful comfortable bra like most of all knix's bras. The return process was amazing because I don't have to package anything up for return and now one of my friends gets to try a great quality bra which I find amazing and very generous of this company to do.
KUKnix US 2.03 days agoHey Jacenta,
Thanks for your detailed feedback! We're glad the medium worked better for you and that you love the comfort. We appreciate you sharing the sizing tip for other customers!
