For a more accurate understanding of the fit, we suggest comparing these measurements with a garment you already own.
1/2 Chest - Lay the garment flat, start 1" below the armhole seam right where the armpit ends and measure across the chest from the right side to the left side.
Shoulder - Measure from the tip on one shoulder across to the tip of the other shoulder.
Sleeve - Measure from the center of the neck to the shoulder tip and down the sleeve to the cuff edge.
Length - Measure from the center of the neck seam down to the bottom hem.
