Speedo Sizing Guidelines
FASTSKIN 3 SIZING
We have updated our sizing to create a simplified global sizing system. With these new products, swimmers should always select sizes by measuring themselves and selecting the correct size accordingly, rather than on their size in previous racing suits.
HOW TO MEASURE
A. Body Loop - Use a tape measure to measure the circumference created by running the tape between the legs and over a shoulder to create a loop. The loop should pass over the shoulder in the same position as where a shirt collar would sit.
B. Chest - Measure the circumference at the fullest point of the bust.
