How to check what size shirt is best for you

  1. Take a shirt that fits you comfortably and lay it flat.
  2. Now, measure the distance across the chest from armpit to armpit. Double the size you get and that is your chest size, or width. 
  3. To find the length, measure from the top of the shoulder along the collar straight down to the bottom of the shirt.
That is it, now you can be sure what size shirt you should order!
