    Great fit

    I love this swimsuit! It has a flattering fit and works well for someone with a larger chest.

    Beautiful, but I had to go up one full size

    I got the floral one and it is stunning. I am 5’4”, 34DD and 135 lbs. I always wear a Knix M+ in everything I have ordered, but because of the compression I had to exchange it for a L+. It really is beautiful!

    Title: Missing Size-Inclusive Photos

    I’m really disappointed that Knix no longer shows swimsuits on models wearing size XL and above. You used to offer inclusive photos, and it made a big difference when choosing what to buy. I already emailed customer service about this, but nothing changed. It’s frustrating to feel that larger bodies are no longer represented. I hope you bring back inclusive model photos.

    Not quite it for me

    It doesn’t quite snatch as needed. While it holds you in it left me with a bit of a rectangle shape. I have more of a shape without it on but still have a mom-tum so was looking for something that would hold that in. Unfortunately i don’t think this is quite it for me. It flattens the chest too.

    Very pretty and retro suit.

    Ruched front on this suit is flattering. The straps are substantial as well. I was hoping to fet the white one as I had a similar suit in the 80’s, but it was sold out!
