    Couldn’t return

    I was disappointed that I was within the window of return time with all of the policies met. The suit did not fit. I sent an email questioning why I couldn’t return the item and didn’t have the courtesy of a response.

    So well fitting!

    Really love the feel and look of this suit - the material is very soft and classy but sculpting. Very happy!

    Not made for the pool

    I love knix swimsuits, I'm actually on my fourth swimsuit. I think the fit is great. But, I'm a pool user, not a beach goer. And these suits do not handle chlorine well. They fade very quickly. So don't use them if you like to swim in pools. Keep them for the beach and sun tanning.

    THE BEST SWIMSUIT I’VE EVER OWNED

    When I saw this bathing suit online I had to buy it right away. The red colour is sexy. The high neck is perfect as I worry about my cleavage. The support is perfect with my generous chest. The clasp is easy to close too! Overall, super flattering. I honestly never thought I would feel sexy in a swimsuit postpartum!

    Nice quality and flattering for athletic build

    I purchased the Oceana in size S. For reference, I am 5'1 and 110lbs with an athletic build. This size fits my body well and I have a petit bust (very flattering). I am recommend this one piece suit! I purchased two, this one and the Leakproof Deep V One Piece Swimsuit. Would recommend both!

    Love the piece!!

    The swim suit is absolutely stunning. I love the colour, and the back is sooo cute. Go a size up if you are a D cup or above in order for it to hold up the breasts.

    Amazing fit!

    I’m in love with the shape of this suit - I usually wear an xl+ bra, and I got the xl and it fits perfect and has amazing support.

    Only downside of this suit is the fabric - the colour is GORGEOUS dry, but as soon as it gets wet it turns a very dark teal (think sweating in a grey tshirt). It’s got two layers so I’m hoping it’s not embarrassing if I get sweaty poolside, but little splashes from drying kids hair, wet faces from hugs, literally anything leaves wet marks anywhere it touches. Love this shimmer but hope this comes out in a regular swimsuit fabric. I’d return if I didn’t love the fit so much!

    So disappointed.

    I don't know whose body this was made for. Admittedly, I have a "long" torso but I'm only 5'5", it's not like I'm way outside the realm of normal. If I pull this up so the shelf bra is even close to the bottom of my chest (still not high enough), the bottoms ride so high up my butt. If I pull it down so the bottoms are still cheeky but comfortable, the side boob is out of control and the bottom of the shelf bra is literally at my belly button. I can't wear this. I love the fabric and colour and style but like, it does not work and I'm guessing doesn't work for a lot of regular shaped people. I'm so disappointed as this is my first ever knix purchase and I bought it on clearance, so can't return. The quality of fabric is definitely there but the cut is so far off. It is definitely the correct size too because the body does fit properly in the middle.
