Measure
your actual body measurements wearing only underwear, using the
image on the left as a guide. This will give you a better fit
than measuring over clothes, or clothes you already have. When
you have your actual body measurements, the table below will give
your size.
Bust: loosely measure around the fullest part.

Waist: measure
comfortably around the narrowest part of waist.

Hips: measure
around the widest part.
