It is buttery smooth and fits me so well. One-pieces can be not so cute but this is cute and fits so well
Love how thick the material is and for once I actually feel supported in a bathing suit. Would definitely reccommend!
This is my second one of these exact swimsuits and i will likely purchase a third! I tell everyone to buy a knix swimsuit.
Your swimwear questions, answered.
Yes, our entire Swim Collection is available for exchange or return. If you’re not happy with your fit, the suits can be returned within 30 days with the sanitary strip intact and tags attached.
Most of our swimsuit styles come in options for A-G cups. Select styles accommodate from an A-DD. Please refer to the side guide on the product page for details.
Yes, some of our suits do have cups that can be removed. Please refer to the “How It Fits” section on the product page for details.
Fit to your cup size for the best support. If there is a dramatic difference between your underbust and hip measurement, we suggest trying the suit on with the sanitary strip intact and tags attached. That way it can be returned or exchanged for a better fit if needed.
