HOW TO MEASURE
It's best to measure yourself while wearing tight fitting clothing or nothing. The tape measure should be snug but not cutting into your body. Make sure the tape measure is level with the ground all the way around - grab a friend or measure in front of the mirror if you need some help.
BUST: Measure all the way around your body at the fullest part of your bust (usually over the nipples).
UNDERBUST: Measure all the way around your body at the top of your ribcage - just underneath the bust.
WAIST: Measure all the way around your body at the smallest part of your waist.
HIPS: Stand with your feet together and measure all the way around your body at the fullest part of your hips (usually just below the hip bones at the top of the buttocks).
Step 1. Measure Your Bust Size
Bend your body forward at about 45°. Take the measuring tape and measure the circumference of your body around the fullest part of your bust, typically where your nipples are.
Step 2. Measure Your Under Bust Size
Stand up straight, then take the measuring tape and wrap it around your ribcage, just under your bust. The measuring tape should be parallel to the ground.
Note:Your Cup Size = Bust Measurement - Under Bust Measurement
