The Heavy Bag Tee in Sea Lettuce

Lay your tee flat on a hard surface. Measure across the chest area about an inch down from the underarm seam, and double that for the full chest measurement.

Measure from the top of the shoulder seam to the end of the sleeve.

Measure straight down the back of the tee, from the center of the neck seam to the bottom of the hem.

Measure around the fullest part of your chest, keeping the tape parallel to the floor. The tape should be snug, but not too tight.

With your arm bent slightly, measure from the base of the center back of your neck, along your shoulder, then over your elbow to your wrist bone.
