Sizing Tips

  • Measure your best-fitting shirt flat for the most accurate width and length.
  • If you're between sizes, choose the larger size for a looser fit.
  • Width is measured across the chest one inch below armpit when laid flat.
  • Length is measured from high point of shoulder to finished bottom hem.
