How to measure:

Bust:
Measure around the fullest part of your chest. Keep the tape measure a little relaxed, so you can still breath without it feeling tight.
Sleeve:
Measure from the top of your shoulder to your wrist.
Waist:
Find the crease in your waist (just above the belly button) by bending to one side, stand up straight and measure from that point around your body.
Hips:
Standing with your feet together, measure around the fullest part of your hips and bottom.
Outer Leg:
Standing straight, have someone measure from the top of the hipbone to your ankle.
Inner Leg:
Standing straight, measure from underneath your crotch to your ankle.
