To measure your waist:

  1. Find the top of your hips and the bottom of your ribs.
  2. Place a measuring tape around your midsection, at a point between the hips and the ribs. Usually just above your belly button.
  3. Make sure the tape is tight but not digging into your skin, and read the measurement.
