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.

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

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

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