To measure your Chest, Waist, and Length, use a flexible measuring tape. For the Chest, measure around the fullest part of your chest. For the Waist, measure around the narrowest part of your torso. For the Hip, measure around the fullest part of your hips. The Length is measured from the highest point of the shoulder down to the desired hemline. Sleeve Length is measured from the shoulder seam to the wrist. Ensure that the tape is snug but not tight for accurate measurements.
