How to find your size

Find your size by measuring your body

Your shirt size is made up of the combination of a collar size, a sleeve length and a fit. You can find your size by measuring your body with just a few simple steps.

  1. Collar Size Place a tape measure at the base of your neck and loop it around. The tape measure should be snug, but not overly tight. This measurement is your collar size.
  2. Sleeve length Hold a tape measure at the center back of your neck. Measure across to the edge of your shoulder, and then down past your elbow and just past your wrist. The total length is your sleeve length.
  3. Fit Measure your chest and waist and compare the measurements against the corresponding options for your collar and sleeve combination. In general, if you prefer a slimmer fit, select the slim fit. If you want a bit more room, select the regular fit.
    • Chest - Measure under your arms, around the fullest part of your chest.
    • Waist - Measure around your natural waistline, keeping the tape a bit loose.
