Reviews Summary
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.

    Shape & Smooth Bra

    Fits great and looks fabulous under tshirts or any other top. Love that the bra gives you shape but doesn’t have an underwire.

    Love

    This fits so well. Leaves me with no back fat the design smooths everything very well. Makes my very wide set breasts sit where they belong. Would recommend!

    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.

    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.
