How to Measure Swimsuit Size

Swimsuit size based on bust, waist and hips circumference
Measure Hips: Measure the circumference around hips and bottom at the fullest part of the hips.
Measure Waist: Measure the circumference of your waistline. Not sure where you waistline is? Your waistline is located just above your belly button. Still not sure? Stand in front of a mirror, and bend to one side. Your waistline is simply where you can see a natural indentation in torso on this side.
Measure Bust: Measure over the fullest part of your bust and all the way around your body. Keep measuring tape parallel with floor.
Measure Torso: Use a flexible measuring tape. Place the measuring tape at a point in the middle of your shoulder. Let the tape continue down across the fullest part of your bust (not through the cleavage). Pass the tape through your legs and take the tape right up your back to the initial starting point (shoulder).
