How to measure

  • Bust — around the fullest part of your bust, tape level.
  • Underbust — around the ribcage right under your bust.
  • Waist — around the narrowest part of your torso.
  • Hip — around the fullest part of your hips and bottom.

Between sizes? Size up for comfort, down for a tighter silhouette. Our stretch pieces are forgiving; PU vinyl pieces (Icebreaker, Heartthrob) have less give, so follow the chart closely. Still unsure — message us with your measurements and we'll tell you which size to order.
