Before you start measuring... remember, size is just a number. Don't suck in or pull the tape measure tight. Stand in a relaxed position, let it all hang out and measure with a taught, but not tight tape measure. It's better to get the RIGHT size than worry about what the size is.
WAIST: Measure between your waist and belly button.
HIPS: Measure around the widest part of your hips.
CHEST: Measure the largest part of your chest. Usually this is where your nipples are.
