How to Measure

HOW TO MEASURE
Grab a tape measure, write down the measurements and compare with our size chart for the right size. For best results, take measurements over your underwear. If your measurements fall between sizes, we suggest that you size up for a better fit.

Chest Measurement

1. CHEST
Holding the tape horizontally measure under your armpits with your arms relaxed at sides, around the fullest part of your chest.

Waist Measurement

2. WAIST
Holding the tape horizontally measure around your natural waistline, keeping the tape a bit loose.
