• When determining your size, you should base it on your own measurements.
• To get the most accurate measurements, have someone else measure you so you can stand relaxed.
• Use a measuring tape, not a yardstick or ruler.
• Wear only underwear.
• Keep the measuring tape straight and snug against your body all the way around. It should be neither too tight nor too loose.
