How to Measure
Shirt measurement diagram with 5 numbered measurements

2. Shoulder Width

Measure straight across the back, from one shoulder seam to the other shoulder seam.

3. Bottom Opening

Measure the full circumference around the bottom hem opening of the shirt — all the way around, not just edge to edge.

4. Shirt Length

Measure from the highest point of the shoulder seam straight down to the bottom hem.

5. Sleeve Length

Measure from the shoulder seam down the outside of the sleeve to the cuff edge.
