First things first. Here's how you take your body measurements.
Grab a tape measure, and take the following measurements:

1. CHEST
Measure the widest part of your chest, usually just below your armpit

2. BELOW BUST
Measure just below your bust, where the underband is placed

3. WAIST
Measure the smallest part of your waist, usually at your elbow

4. HIP
Measure the widest part of your hip, usually just above your seat

We recommend measuring yourself in your undies for the most accurate result.
