Sleeve: Measure from the center back of your neck, across the shoulder, and down to the wrist with your arm slightly bent.

General Sizing Tips

  • If you're between sizes, we recommend sizing up for a more relaxed fit.
  • For a closer, more fitted look, choose your exact size.
  • All measurements are approximate and may vary slightly by style.
