Pick your size with confidence. This hub explains how to measure and links you to the correct size chart for each product type.

Important: Size charts are garment-specific. Always use the chart linked from the product page (or the matching chart below).

How to measure (fast + accurate)

  • Chest width: measure across the chest about 1 inch below the armhole (or measure your chest circumference where the chart says “chest to fit”).
  • Body length: measure from the high point of the shoulder to the bottom hem.
  • Sleeve length: measure from the center back of the neck to the sleeve hem (for hoodies/long sleeves).

Fit tips (so you don’t guess wrong)

  • Between sizes? Size up for a roomier fit.
  • Prefer a fitted look? Follow chest measurements closely and compare to a shirt you already own.
  • Gift sizing? When in doubt, a size up is usually safer.
