    Great suit- one suggestion

    This suit is fun and fits great- however it would be fabulous if the bra liners were white. When the suit is wet the beige liners stand out like a sore thumb. White liners would allow the top to keep a unified colour even when wet.

    Size up

    Beautiful swimsuit, but sizing is a bit off. I have a pear shaped body and the bottom was too compresing, had to return. Sad, since the bathing suit is beautiful

    Very flattering swim suit

    This is my second swim suit from Knix and I love it! Very flattering cut. The bottoms are high rise and hold you in nicely and the one-strap top looks great on my shoulders. I'm thinking of ordering the two piece, one-strap bikini too!!

    very pretty and well made but TOO TITGHT!

    The color of the bathing suit and the overall design are very nice and well done. However, the elastics are too tight, making me feel like I’m wearing a straitjacket. I understand that it should be snug initially, but this feels excessive. Currently, I’m stretching it out by hanging it over the back of a chair.

    Runs small

    I love this swimsuit but unfortunately I have to return as it’s way too small. The reason I ordered said size is because I saw it on a model who is my size if not a big larger so I figured I’d be safe. I ordered a XXXL (size 24-26) and I’m usually an XXL (size 18).

    Excellent

    I wasn’t expecting this suit to be flattering. I love the fit and the support is perfect. Looking forward to wearing this on my beach adventure.

    Bathing suit

    I love the look and feel of the suit. The only recommendation I would make is that the elastic on the leg opening needs to be a little more tight
