Chest — Place tape measure under your arms at the fullest part of your chest, wrap around your body until your fingers meet and mark the measurement.
Waist — Measure around your natural waistline - right above your hips. Be careful not to squeeze too tight to allow a little give.
Hips — With your feet together, measure around the fullest part of your hips to ensure you'll have enough room to move comfortably.
