It's best to measure yourself while wearing tight fitting clothing or nothing.
The tape measure should be snug but not cutting into your body.
Make sure the tape measure is level with the ground all the way around.
BUST: Measure all the way around your body at the fullest part of your bust (usually over the nipples).
UNDERBUST: Measure all the way around your body at the top of your ribcage - just underneath the bust.
WAIST: Measure all the way around your body at the smallest part of your waist.
HIPS: Stand with your feet together and measure all the way around your body at the fullest part of your hips (usually just below the hip bones at the top of the buttocks).
If you we don't make your size, there's a good chance we make your sister size! Most people find they are easily able to wear their sister sizes so we recommend using the table below to choose your size.
