Need help finding your perfect fit? We’ve got you.

Doll Behavior pieces are designed to hug curves, turn heads, and make you feel like that doll. Use the size chart below to find your best fit.

If you're unsure, we recommend sizing up for more coverage—or reach out for a personalized suggestion.

Fit Notes

  • Our swim fabrics are stretchy and flattering, but not all styles offer the same support.

  • Strapless and micro tops provide a more revealing, fashion-forward fit.

  • High-cut bottoms and cheeky styles are standard in this collection. Size up for a more modest fit.

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