  • Wearing a bra. Place the tape around the fullest part of your bust.

  • Place the tape around the narrowest part of your natural waistline.

  • Place the tape around the fullest part, usually over your bottom or at the top of your thighs.

  • With your arm bent, hold the tape on your shoulder bone and measure over your elbow to your wrist

  • In bare feet, stand against a wall and mark the point perpendicular to the top of your head. Measure up to this point from the floor. Be sure to ask first if the wall doesn't belong to you.
