Jacket Sizing Guide - Measuring (Women's)
Tip:if you don't have a measuring tape, you can use a ruler and a piece of string
Measure around the chest at the fullest point of the bust, keeping the tape parallel to the floor.
Measure around your natural waistline. This is typically located about an inch above your bellybutton and should be the narrowest part of your torso.
With arm relaxed at your side and slightly bent, measure from center back neck, over the shoulder, down the outside of the arm to the wrist. Sleeve length is always in whole numbers so round up if necessary.
