How do I measure my sleeve length?

1. Place one of your best-fitting shirts on the back of a flat surface.
2. Measure from the center of the collar to the shoulder seam.
3. Measure from the shoulder seam to the end of the sleeve, measure to the point where you want the sleeve to stop.
4. Add the two measurements together to get the length of your sleeve.

Be careful, the double cuffs are not unfolded. Illustrated instructions can be found here.
