How to properly measure your pelvic circumference ?

Follow the steps below to know your pelvic circumference measurements :

  • Take a flexible tape measure.
  • Pass the measuring tape straight around your pelvis, at the widest point of your buttocks.
  • Check that the tape is well placed around the entire circumference of your pelvis, straight and parallel to the ground.
  • To be as accurate as possible in your measurements, you must be able to pass a finger between the tape measure and your body.

Are you hesitating between two sizes ? Take the largest size.

If you have taken your measurements and are between sizes, we recommend sizing up. The bottom will thus be more adapted to your body shape and you will avoid feeling uncomfortable in bottoms that are too tight.
