All you need is a tape measure! While it’s easiest to have someone else take your measurements, it can be done by yourself. Just stand in front of a mirror so that you can see that you have the tape in the right position.
Ideally, you should be measured wearing only your undergarments. Do NOT measure yourself wearing jeans, sweats, or other bulky clothing. It DOES make a difference!
The tape should not be too loose. Just wrap the tape around the area of the body being measured and hold it in place. You should be able to put a finger behind the tape, but no more than that.
Bust: Measure the circumference of your chest. Place one end of the tape measure at the fullest part of your bust, wrap it around (under your armpits and back to the front) to get the measurement.
Waist: Measure the circumference of your waist. Use the tape to circle your waist (sort of like a belt would) at your natural waistline, which is located above your belly button and below your rib cage. (If you bend to the side, the crease that forms is your natural waistline.) Don’t suck in your stomach, or you’ll get a false measurement.
Hips: Measure the circumference of your hips. Start at one hip and wrap the tape measure around your rear, around the other hip, and back to where you started. Make sure the tape is over the largest part of your buttocks.
Upper arm: Measure the circumference of your arm. Wrap the tape measure around the widest part of your upper arm from front to back and around to the start point.
