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!
Bust
Measure around your chest at the fullest point of your bust with no bra.
Waist
Measure around the narrowest part of your waist.
High Hip

Beautiful loved it and it came really fast
This was my first Bydee purchase (along with the matching Santos bottoms) and I couldn’t be happier! The design, beading, attention to detail and quality is unmatched. The top fits true to size and is so comfortable, will definitely be purchasing more bikinis from Bydee!
