Size & Fitting

Women's Clothing and Swimwear Size Information

HOW TO MEASURE:Measure your waist and hips and compare to the size chart below. If you are between two sizes, we suggest selecting the larger size. XS-XL sizes correspond to the numerical sizing on this chart, unless specified in the description of the garment. To get the most accurate measurements, have someone else measure you. Be sure to hold the measuring tape straight and snug, not tight, to your body.

BUST:Measure over the fullest part of your bust, with the tape measure parallel to the floor. This measurement will assist you in determining your swimwear or clothing size for tops and dresses.

UNDERBUST: Measure directly under your bust, with the tape measure parallel to the floor. This measurement will assist you in determining your bra band size and swim top size.

WAIST:Measure around the narrowest part of your natural waistline.

HIPS:Measure around the fullest part of your hip, before the thigh begins to narrow. This measurement will help you determine your size for skirts, pants, and form-fitting dresses.

Bikini Top Sizing Chart:


In order to make your customer experience better, Sandi's has a new size chart where all we need from you is your bra size!

Ready for a day at the beach in your new bikini? For swimwear tops that have a cup size, simply order your usual bra size (band + cup), our system will do the rest. Finally, you will receive a bikini top that has a letter designation and possibly a bra band/cup size.
