How to measure

  • Body Chest: Measure around the fullest part of your chest, keeping the tape level.
  • Garment Width: Lay a similar shirt flat and measure straight across the chest.
  • Body Length: Measure from the highest point of the shoulder down to the hem.

Measurements may vary slightly. If you prefer a more relaxed fit, size up.
