Not sure which size to grab? Start here. All measurements are body measurements in inches — measure around the fullest part of your chest (just under your arms) and around your natural waist (the narrowest point above your belly button), keeping the tape level and snug, not tight.

Between sizes? Size up for a looser fit. Still stuck? Contact us and we'll help you pick — and remember, every order is backed by our 30-day returns and 105% money-back guarantee.
