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.

- Rated 5 out of 5 stars19 hours agoBest Bra ever !
I was very skeptical about the sizing but after chatting with the online pro I decided to go for it. It fit beautifully! Most comfortable bra I’ve ever worn. I will be ordering more.
JKJill K.Verified BuyerReviewingShape & Smooth Bra - Rated 1 out of 5 starsYesterdayToo tight
I measured as per instructions and both bras I ordered are too small - too tight around my chest. I have ordered a 2” extension hoping that will resolve the issue.

Fits nice and snug
MGMarlene G.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 stars2 days agoComfy
If for most of the day I'm not noticing it, and I'm not feeling like a my back is kinked than it's a good bra.
I do pull the straps in more because I'm broader shoulders and longer wingspan so the sizing is always harder to match in clothing for me perfectly. That does leave me with some marking w/o discomfort.
HDHolly D. R.Verified BuyerReviewingShape & Smooth Bra - Rated 5 out of 5 stars3 days agoNew
This has been one of the hardest bra to get use too. I did the measurements of my breast and it was a large. It is really tight and where I thought my under arm fat would be held up as well as my breast support it overlaps a lot. I feel very uncomfortable wearing it.

love the color. I've only wore it once, great support so far.
LLynnReviewingShape & Smooth Bra - Rated 5 out of 5 stars1 week agoComfortable and very good at smoothing out the back
This bra works. It feels great and I like the way the insets are fixed and don't move when washed That is a great improvement for me Looks good.

CLChristine L.Verified BuyerReviewingShape & Smooth Bra - Rated 1 out of 5 stars1 week agoDoesn’t fit right
I followed all the directions for sizing, but I still find this bra doesn’t fit quite right I find it comes too high under the arms

Support, comfort, super soft it feel like barely there and like the color, is pretty and even do the straps are slim they do give Support and does not leave any sort of mark or indentation on your skin. Nice
CCCarmen C.Verified BuyerReviewingShape & Smooth Bra - Rated 4 out of 5 stars1 week agoSomething new
Knix has been my only experience with wireless bras. I'm a 38G, but found that in these bras I needed a bit more cup coverage. At first I tried the wingwoman bra and while I liked it, I didn't love how my boobs always ended up coming together and had some spillage above the cup itself. So we tried this one. Had to size up, but have since purchased 4 more. They are fairly comfortable. I would probably try the wire if it was offered in a bigger cup size, only because I still crave the separation of a weird bra. But I was tired of my old brand snapping on me and wanted desperately to find something different. For the time being this is definitely it. Will continue to purchase these along with the period panties, which I have worn for years. Something very satisfying in having them be more matching again. Customer service is AMAZING btw!
