    Flattering swimsuit

    I just received 2 of these swimsuits, 1 Lotus and 1 Black. Im 5'7", wear a 40DD Knix bra and bought a XXL+. This swimsuit fits perfectly, it is flattering in all the right places, comfortable, holds me in nicely, but not too tight.

    Comfortable and Flattering, are 2 words you wouldn't usually hear me say about a swimsuit on my body!

    Thank you Knix!

    Love

    I bought this along with the classic one piece and love both. This one is super comfortable. Great material, the V isn’t too low and makes the chest look fantastic. I decided to have a little fun and go with the pattern which I’m still adjusting to cause I generally go for solids, but I already got the classic in black. It’s not too crazy a pattern so I will stick with it but I absolutely love this suit. It doesn’t move and it’s soooo comfortable. Another winner Knix!!! Wish I had purchased your suits earlier in my life. Would have saved me a lot of heartache and money!!

    Flattering

    The suit fits well and is figure flattering, plus I ocean-tested it and it stays put while jumping in and getting out of the water.

    High quality and perfect fit. I wear a large bra, and ordered a medium swimsuit. Absolutely love it. Planning to purchase another one.
