How to measure fitting model?
Measure all the way across your back, from the tip of one shoulder to the tip of the other. Try not to hunch over!
Wearing your usual bra, with arms relaxed at your sides, measure your bust at the fullest point, keeping the tape parallel to the floor. It takes it past over both nipples, UNDER the underarm, OVER the shoulder-blades, and AROUND your back about where your bra strap is.
Measure around the narrowest part of your natural waistline. To find your natural waistline, bend to one side; there should be a crease where you bend (often it’s below your rib-cage)–that’s your waistline. It’s OK if it’s higher than where you normally wear your pants but it’s SO important for getting a great fit!
Standing with heels together, measure around the broadest part of your hips (this includes the broadest part of your butt).
Slip out of your shoes, stand with your feet slightly apart and your back to a wall, and measure straight from the floor to the top of your head.
