How to Measure

  • Bust: Measure around the fullest part of your chest, keeping the tape horizontal and flat against your back.
  • Waist: Measure around your natural waistline (typically the narrowest part of your torso, about an inch above the belly button).
  • Hips: Stand with your feet together and measure around the fullest part of your hips and rear.
  • Note: This chart is based on body measurements. Actual garment measurements may vary slightly depending on fabric elasticity and style.
