Swim fabrics stretch a bit when wet, so sizing down or staying true to size is better when you’re spending
most of your time in actual water.

Bikini Sizes
To determine your correct bikini size, you need to (1) take accurate measurements of your chest
(bust and under bust), waist, and hip circumferences, and (2) calculate your bra size. Write down
your measurements in inches and centimeters. Then, refer to the size chart above to find your
corresponding size. Keep in mind that these are approximations so the fit may still vary.

Measure bra size correctly
When it comes to bikini sizes, knowing your bra size is very important if you want to find a well-fitting two-piece swimwear. To accomplish this, you need to take measurements of your (1) bust and (2) under bust circumferences.
You’ll need a reliable measuring tape for accurate measurement-taking. You can also use a string or a cord to wrap around the body and just measure it with a ruler afterward. If possible, find another person to help you. Make sure you inhale briefly and hold your breath before measuring. The measuring tape should rest horizontally and loosely; it must not press into the skin. Otherwise, you might get a size that’s too small for you. From there, you can determine your corresponding band size and calculate for your suitable cup size.

Bikini under bust measurement
Your under bust is necessary to determine the band size of your bra. Measurements are usually
taken in inches and are rounded off to the next even number. For example, a 31.5-inch under bust
measurement fits a 32-inch band size.
Knowing the under bust circumference is also needed to calculate the cup size.

Bikini bust measurement
A bikini’s cup size is the difference between the under bust circumference and the bust
circumference – the highest point of the chest area. Once the values are subtracted, the resulting
answer translates to an equivalent letter. For example, a bust measurement of 34 inches and
under bust measurement of 32 inches has a difference of 2 inches, which is a B cup.
