Sweatshirt size guide:

For the best fit, compare these measurements with a sweatshirt you already own that fits comfortably.

Lay your sweatshirt flat without stretching:

• Length: Measure from the highest point of the shoulder, beside the neckline, down to the bottom hem.

• Width: Measure straight across the chest from one side to the other. This is the flat garment width, not your chest circumference.
