    Great

    Got the Autumn Court fabric and it's gorgeous!

    I had to return for a larger size. I used the size chart to order but still found my alleged size too small, but the exchange was fast and easy.

    Bathing suit is flattering and stays up well even without the straps

    Swimsuit

    I really like the swimsuit but I find it is a bit snug. I am hoping with some use it will be a bit more comfortable.

    It looks great on!

    Great Swimsuit!

    Great suit, very flattering. Deducting one star because while the concept of having convertible straps so you can wear in many styles is great, the execution is slightly lacking - I find every time I'm putting the suit on or taking off, the straps come unhooked and they are very difficult to re-hook especially if they've come undone in the back.

    Runs small and cream fabric is see-through

    It’s a nice fit and flattering, I sized up to a L. Unfortunately, it’s see-though.

    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.
