Speedo swimsuits are designed to have a close fit to your body to help you have the best swim. If you would like a looser fit you can go up a size.
Our swim shorts sizing is based on your waist measurement in inches. Swim shorts with an elasticated waist have a bigger size range as they stretch a little more.
