Size Guide

For the most accurate measurements, use a soft measuring tape and wear minimal clothing. Stand naturally and breathe normally.

  • Bust: Measure around the fullest part of your bust, keeping the tape parallel to the floor. The tape should be snug but not tight.
  • Waist: Measure around the narrowest part of your natural waistline, typically just above your belly button.
  • Hips: Measure around the fullest part of your hips and buttocks, keeping the tape parallel to the floor.

If you're between sizes, we recommend sizing up for comfort.
