Apparel Sizing Tips:

Use these tips as a general guide when finding your measurements:

Chest/Bust: With your arms at your sides, measure around the fullest part of your chest, across shoulder blades and under arms.

Waist: To measure your natural waistline, wrap the tape so it intersects your navel. Keep tape flat, but comfortably loose.

Hips: Stand with your heels together and measure the fullest part of your hips. Make sure the measuring tape is level all the way around your body.

Inseam: Stand up straight, and start the tape measure high in your crotch. Straighten the tape down the inside of your leg to the bottom of your ankle.
