How To Measure
For bust size measure under the arms at the fullest point of your bra cup. Don’t forget to go underneath your arms and not around them.
Measure around the natural waistline, which is the smallest part of your waist.
Standing with your heels together, measure around the fullest part of your hips. Make sure you keep the tape straight and parallel to the floor.
Make sure you are in a pair of pants that fit you well and also bare foot. Then take the measurement from the crotch seam down the inside of the pant leg. (Inseams may vary depend on the style of pant leg.)
