    Feminine and practical

    I’m an XS in Knix sizing (30B, 48kg, 156cm) and the M fits me like it does on the model in the product carousel. I’m glad I listened to the other reviewers by going up two sizes up because they’re right, the sizing is way off. There’s a second elasticized layer across the bust that isn’t padded so it can accommodate a bikini top underneath but is also not necessary. I haven’t worn it on the water yet, but the fabric feels soft with a tight weave so should protect me from the sun (which is why I got it). I like that unlike other rash guards on the market, this one looks more feminine and versatile. Got this on sale and don’t regret it.

    Super cute, tight fit

    Really cute rashguard! Nice coverage when keeping the drawstring down and looks great if pulling it up to expose more midriff. I’d also suggest sizing up as other reviewers mentioned. My measurements would be considered a small and the medium fits tight but comfortable (basically how you would want a swim suit to feel). I’m 5’7 and 130lbs, 34B for reference.

    Sizing is way off

    I have been a loyal Knix fan for years now, but they really missed the mark on this one. The sizing is completely off. I ordered the size large (I’m normally a medium) and I can’t even get it over my head. Sadly, I purchased during the warehouse sale and cannot exchange.

    Love this top, the arms are a smaller fit, i find you really need to line up the seams as youre putting it on, not afterwards but the rest fits to size. This top is great for SUPPing, comfortable, great quality. I wouldn’t mind if the elastic in front went a bit higher for versatility but overall very flattering, beautiful colour too!

    Just what I needed

    I work on the water and needed something that would be functional/comfortable, work appropriate and provide rash guard specifically. Even better that it helps protect from the sun. Originally I had purchased a L following recommendations from the size chart but exchanged for the XL and am much happier with the fit.

    Well worth it!

    I love these so much… I bought two! I was a little surprised that I needed to go up two sizes but it was well worth the effort to exchange. The material, fit, and detailing are perfect.

    At first I loved it, but then I used it

    It’s super cute and wonderful when you first get it - but it started to lose its colour after using it once. I’ve used it twice now and it is practically white in some places. I don’t feel comfortable using it again. It now feels see-through. I feel like I’ve wasted my money.

    Very cute! Can be worn as a top with jeans or as a rash guard. Offers peace of mind in the sun. Takes a while to dry. Plan accordingly.

    Cute…Size Up

    I recommend sizing up at least 1 size possibly 2 in this top. My daughter is a size 6 and a 34D and we ordered a medium. She was well within the measurements listed to wear a medium and it was way too small. We exchanged it for a large and it was way too small as well. We are now waiting on an X-LARGE and hoping it will fit. Thankfully my teen doesn’t care about sizes, but many people it would offend wearing multiple sizes bigger than you normally are.
