How to take measurements for sizing?
To determine your correct size stand upright in front of the mirror. You will need a tape to take measurements. Try to keep the tape leveled during measurements. Best practice is to use help. You will need at least three measurements in order to find out exact size for you. Measure following things:
Bust measurement starts under your armpits, go over your shoulder blades and over the bust. Don’t pull the tape measure too tight. For fitting a bra, you also need the measurement just under your bust.
Measure around your natural waistline about an inch above your navel. Don't try to pull your belly in. Try to stay relaxed.
Take hip measurements about 8 inch below your waist.
Based on your measurements follow the sizing chart:
