    Cute but too thin up top

    I bought this to be my modest bathing suit after having breast surgery but found the top fabric quite thin and showed my nipples too well.

    Weird sizing

    The sizing doesn’t work for me. Unfortunately it turns out it was final sale (I wasn’t aware at time of purchase). So now I’m stuck with a $100 bathing suit I can’t wear, which I bought to use while undergoing radiation treatment. This is my second - and last time - I will order anything from Knix.

    I love it

    Thanks for making this swimsuit - for anyone looking at the zipper comments, it's a great zipper actually !

    When you lift it up it zips way down but if it remains downwards it stays put wherever you decide.

    Im glad I bought it :)

    Cute for poolside but…

    This suit is super cute and the fabric was of good quality, however I returned because I felt like the zipper was too large and loose to keep the suit completely closed if I chose to wear it down slightly from being fully zipped. I wanted to use the suit in a water aerobics class and I didn’t think it would work well for that.

    Great suit with minor flaw!

    I love this suit! I’m 8 months postpartum and do not have my body back like all the reels suggest I should. This suit offers coverage where I want it (butt, hips, upper arms), and I love the zipper option! However, I find that the zipper does not stay in place when I want it half zipped, however. It’s either all boob or none. I am a D cup, so maybe all the smaller chested people out there wouldn’t have the same problem. If there was a middle zip option for me, it would be the perfect sexy, athletic, modest suit of my dreams. The colour blocking on the hips definitely gives it a flattering shape. As advised in the reviews, I sized up and that was the correct choice. A bit of nip can be visible because there is no padding, but who cares? Not me.

    Super cute but lacks bra support and butt coverage

    Super cute pattern and style and slimming design, but when someone wants a full coverage suit like this one, they are likely not looking for “cheeky butt coverage” . Put in a soft cup bra for more support and better bottom coverage and you have the perfect suit!

    Saddest human

    I love the look of this swimsuit. I ordered it the moment I saw it and it actually fit my long torso and I was SO PUMPED (5’7 155 lbs 36DD size XL). Annnd then I looked in the mirror and couldn’t help but notice the lack of cups/liner and was SO SAD when I discovered there wasn’t even a spot to insert them myself. I mostly swim in a freezing pool with 1 million kids so visible headlights are not the vibe I’m going for. The top support is otherwise decent but I did find the bottom coverage a smidge narrow.

    Love this suit

    Love the coverage of this suit but size up. I originally ordered a large but couldn’t do the zipper up and then found it difficult to take off. I have since ordered a XXL and it seems to fit perfectly.
