    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!!

    Really wanted to like this but too tight on the shoulder

    I was so looking forward to getting this suit. Splurged on myself for an upcoming vacation and had seen a plus sized influencer wear who looked great in it. I’m in between L/XL normally and got the XL based on the size chart and reviews of it being tight.

    The fabric is very thick and supportive which I didn’t mind and definitely needed for a one shoulder suit, but the one arm that has the O ring strap was just too tight and pulled very hard on my shoulder. If the circumference of the at area had been larger I think I would have kept it. I do have larger arms so could be just a me problem. It became quickly uncomfortable after only a few mins of trying on. Can’t imagine wearing that for a day at the beach or pool. I feel an XXL may fit too loosely on my lower body so unfortunately will have to return.

    I’m sure there are many others this suit will be great on. For me I’ll keep searching. Sadly won’t let me upload my phot for reference.

    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.

    Good looking suit

    As the other reviewer mentioned - this one runs small. I’m usually an 8 in most standard size clothing. I ordered the medium. It was too tight, however - it was ultra easy to return and I had the next size up at my doorstep one business day after I returned the smaller size. For reference I’m 5’4 and 155lbs. I have a long torso so that might have contributed to the size issue.

    The padding on the top is a beige colour - so you can see the pads through the white top. I’m going to see if I can find white ones so they aren’t as obvious - not a deal breaker, but something to consider.

    Over all it’s a flattering one piece, and feels a bit ‘different’ while still providing good bum coverage and added support on the bottom half.

    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).
