How To Measure Your Size

Be sure to keep the tape level, and not too tight. Then use the chart as a guide, but allow for some variance based on how you prefer the garment to fit.
WAIST: Find the top of your hip and measure the full circumference around your body.
HIP: Stand, feet together, and measure around the largest circumference at the hips.
