How to measure yourself

General instructions:

  • When measuring making sure the tape is snug and not loose but also not digging into the skin.

  • Make sure the tape is parallel to the floor

  • Ideally measure yourself as close to the skin as possible

Mid-Waist: Measure at your mid-waist location i.e. 1-2 inches below your belly button

Hips: Measure at the widest part of your hips, going over your bum.
