Bust Measurement :
Measure over the fullest part of your bust, with the tape measure parallel to the floor. This measurement will assist you in determining your size for tops and dresses.
Measure around the narrowest part of your natural waistline. Measure around the fullest part of your hip and but, before the thigh begins to narrow. This measurement will help you determine your size for skirts, pants, & dresses.
Starting at the front part of your shoulder, run the tape down your back, in between your legs and up over the fullest part of your chest, ending at the starting point.
