A. Bust
Wrap a measuring tape around the fullest part of your bust, keeping it level with your back. Ensure it's snug but not tight for an accurate fit.
B. Waist
Find your natural waistline by bending to one side; the crease is your waist. Measure around this point, keeping the tape comfortably snug.
C. Hips
Stand with feet together and measure around the widest part of your hips and buttocks. Keep the tape straight and level for the best fit.
