Measure your lower waist and hips to choose your best size.
Waist (Lower):
Find your lower waist (where your waistband naturally sits).
Wrap the tape snugly—firm but not tight.
Hips:
Measure around the widest part of your hips (fullest part of your bum).
Keep the tape straight and level.
Helpful Tips:
Tape should be snug without squeezing.
If waist and hip suggest different sizes for bottoms, choose by waist (lower).
