Size Chart

A - Chest - Measure chest at the fullest part. Measure all around the body (total circumference).

B - Waist - Measure the waist where the body bends.  It helps to bend side to side to identify exactly where to measure.  You can put an elastic band around the waist to mark the correct placement.

C - Hip - Measure the hips at the fullest part, usually around the seat.

D - Back Waist Length - Measure from the base of the neck (in the center, not the side), to the center of the waistline.

F - Shoulder Width - Measure between the tips of your shoulders at your acromion bones, where a sleeve seam of a normal t-shirt would be. 

G - Arm Length - Measure from the top of the arm (find the bone at the shoulder/top of arm) to the wrist (find the bone at the side of the wrist), WITH THE ELBOW BENT.  It's important to keep the elbow bent to allow for movement when you make a sleeve.
