Boys Shirts

Boys shirts are sized by collar, so a collar measurement is the starting point, but always check the chest measurement too.

How to measure the collar

  1. Measure around the base of the neck, where the shirt collar will sit.
  2. Keep two fingers between the tape and the neck so the collar isn’t too tight.
  3. Also check the garment chest measurement in the chart, a shirt fits on both the collar and the chest.

Keep the tape comfortably snug, never tight, a tight measurement leads to a tight fit.
