Sports Illustrated Swim 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 to 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.

How to Measure

SPORTS ILLUSTRATED SWIM FIT GUIDE

These suits run true to size.

Between two sizes? We recommend choosing the smaller size as swimwear tends to stretch when wet.

ONE-PIECES: If you're petite with a shorter torso, we recommend sizing down. However, if you have a longer torso, we recommend sizing up for the best fit.

BIKINI TOPS: Bra sized tops, order your normal bra size. For other tops, refer to the product’s description for a specific size’s cup capacity.
