We suggest measuring four key points on your body to find your perfect size. It's best to wear as little clothing as possible when taking these measurements. We recommend holding the measuring tape flush against your body, ensuring not to pull too tightly for the most accurate measurements. If you don't have a tape measure, you can use a piece of string and measure it with a ruler afterwards!

Omg this has got to be one my of favorite swimsuits ever! The beadwork and detail is incredible, and the design is so beautiful and unique. I got so many compliments and loved wearing it on my euro summer trip. The fit is true to size, and has thick material and padding, and not see through. Buy it for your next vacation!
The beading detail… just absolutely breathtaking
Loved it! I thought it was high quality and supportive. I’m a 32D/34C and 105lbs and got a medium
Bought a few swimsuits for my bride-to-be and this was the standout. She wore it in Hawaii, and it looked incredible in our honeymoon photos. She felt amazing in it and so did I seeing her wear it. Would buy again in a heartbeat.
Love Bydee bathing suits , material is top notch!!
