    Good fit

    This is the best fitting bra I have purchased from Knix.

    It gives me secure support and keeps my bosom in place. It looks good and it’s very feminine.

    Favourite Bra Ever

    I bought the beige Shape & Smooth bra first. I loved it sooooo much I ordered all the other colours available. I have 10 other different Knix bras which I also like very much but the Shape & Smooth is my absolute favourite!! It’s very supportive, smooth and comfortable. It’s flawless under any type of short/blouse. I hope they design more in other colours in the very near future.

    Didn't work for me

    The sizing was way off. Originally went for a L based on the auto recommendation. It was so tight around. Exchanged for the next size up, and the cup was huge.

    Comfortable coverage

    I’ve had difficulty finding the perfect bra until I tried the Knix Shape & Smooth bra. After buying one in store, and wearing it for a few weeks to make sure it was comfortable, I immediately ordered two more online when a sale came up.

    My go to

    This has been my go to bra for some time now. It’s not the most supportive and it does lose its support somewhat quickly for the price, but it’s so incredibly comfortable.

    Too small

    I went with my size of bra that I usually wear. Which is 36DD

    But it was too small so I returned it

    Love this bra!

    I have a couple of Knix bra styles and I have to say this may be my favourite fit! It is so smooth and so comfortable and provides great support too. I usually buy Wing Woman, but the fit has not been consistent, so I thought I’d try this style - so happy with it.

    Well done Knix!!

    This bra holds really well for large busts. They also finally understood to put larger straps on large size bras, no digging in the shoulders anymore!

    I also like the extra fabric on the side keeping the overflow in, bonus!!!

    Too Small!

    Every bra now seems to be a different size than the last. A bra style that fit previously no longer does (NO weight changes!). They also now seem to be made of a more rubbery-type of material. These bras are expensive, and this is all very disheartening.
