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.

Customers say this bra is very comfortable and offers excellent support without underwire. Many highlight the great fit and smooth appearance under clothing, with side and back panels providing good coverage. The molded cups and seamless design appeal to those seeking all-day wearability. Common feedback addresses sizing inconsistencies—some note the band runs tight or cups fit small, while others mention it fits larger than expected. A few mention the armpit area sits high or straps could be softer. Most customers praise the quality and say they'd repurchase.

- Rated 5 out of 5 starsYesterdayLives up to its name
This bra does exactly what its name says, and it does it comfortably. So many of today’s bras sacrifice shape and support for comfort but this one does it all. This is now my daily go-to bra. More colors please!
NLNancy L.Verified Buyer - Rated 5 out of 5 stars2 days agoThis one’s a favourite
Secure but comfortable support. Feels so nice on the skin.
GLGina L.Verified Buyer - Rated 5 out of 5 stars3 days agoShape & Smooth Bra
These bras feel so good and fit amazing! Whether wearing it casually or as a sports bra! Game changer…no more wires! My only disappointment was they didn’t have more colours available in my size in the store cuz I would have bought them all!!
LBLouise B.Verified Buyer - Rated 5 out of 5 stars4 days agoConfort
Super confortable et bon maintien toute la journée, les bretelles ne tombent pas et pas de douleur.
NTNoémie T.Verified Buyer - Rated 5 out of 5 stars4 days agoWhat I’ve been waiting for
I absolutely love my Knix bra! It is so comfortable and supportive, and it fits beautifully. It gives me the support I want without feeling uncomfortable or restrictive. I can wear it all day and honestly forget I even have it on! Definitely one of the most comfortable bras I’ve owned, and I would highly recommend it!
AHAndrea H.Verified Buyer - Rated 5 out of 5 stars5 days agoNew favorite!
Great coverage and comfort all wrapped into one.
KSKim S.Verified Buyer - Rated 5 out of 5 stars5 days agoGreat fit and soooo comfortable!!
Great fit and soooo comfortable!!
PKPhyllis K.Verified Buyer - Rated 5 out of 5 stars5 days agoGood fit
I have tried several styles of knix bras and this is the best fitting. Fortunately I took a chance and ordered two. I had had a lumpectomy a couple of months previously and was told to get a good supportive bra. I just didn’t expect it to be so pretty.
PPattyVerified Buyer - Rated 5 out of 5 stars5 days agoShape & Smooth Bra
Best wireless bra. Smooths the back and no uniboob in the front. I’ve tried so many wireless bras hoping to find the perfect fit. With this one you actually get two separate boobs. Not two squished together. Longer bands roll up on me and none of that here either. Great job Knix 👏🏻
JJJudy J.Verified Buyer - Rated 5 out of 5 stars6 days agoShape and smooth bra
True support, nice fit, covers my back fat, feels good on.
CBClaudette B.Verified Buyer - Rated 5 out of 5 stars1 week agoHighly recommended
I own this bra is 5 colours. Highly recommended
KPKatrina P.Verified Buyer - Rated 5 out of 5 stars1 week agoGives breasts a nice lift and shape
This bra gives breasts a nice shape and lift, however after trying many different sizes I had to return the bra because I couldn’t get a good fit, either I had bulging at the top or the band was too loose. I really wanted it to work because it’s a very nice bra.
