Supplier-provided measurements might differ by up to 2 inches (5 cm).

A useful tip is to compare these measurements with one of your own garments at home by measuring it similarly.

A Length

Begin at the collar on the top (high point shoulder) and draw the measuring tape down to the garment's bottom.

B Width

Start the measurement at the seam right below one sleeve and extend the tape across to the seam underneath the opposite sleeve.

C Sleeve length

Position the tape at the top of the set-in sleeve and extend it down to the sleeve's hem.
