HOW TO MEASURE - SHIRTS/JACKETS
CENTER BACK LENGTH

Lay the shirt/jacket flat back side facing up and measure the center back length from from below the collar down to the bottom.
CHEST

Lay the shirt/jacket flat front side facing up and measure the chest from side to side at the armpits. Make sure to measure from edge to edge (not from seam to seam), because a small part of the back side may be visible when laying flat and this should be included to get the full width.
SHOULDER

Lay the shirt/jacket flat back side facing up and measure the shoulder from shoulder seam at top of armhole to the other side. Make sure to measure the shoulders at the widest point.
BOTTOM

Lay the shirt/jacket flat front side facing up and measure the bottom from side to side at the lowest point at the edges. Make sure to measure from edge to edge (not from seam to seam), because a small part of the back side may be visible when laying flat and this should be included to get the full width.
SLEEVE

Lay the shirt/jacket flat front side facing up and measure the sleeve from top of armhole to sleeve opening. Make sure to include the cuff.
