Bust- This is not your bra size Wear an unpadded bra (your dress will have a built-in bra) Waist- Find the natural waist, this is the smallest part of the waist Usually about 1inch above belly button, keep tape slightly loose to allow for breathing room Hips- Find the widest part of the hips Usually about 7 inches below natural waist, tape should brush across both hipbones. Note: 1. Manual measurement Easily Lead to 1-3cm errors (1cm= 0.394 inch, 1inch=2.54 cm). 2. The swimwear was measured after streach , and it is body size chart. 3. Color may be little different due to monitor, thanks for your understanding.
