Top Sizing (Without Underwire)

Our unstructured tops are designed with adjustability in mind—allowing you to customize both fit and coverage to your preference. Because of this, sizing is not limited to a single cup, but rather a range.

As a general guide:

  • XS–S: best suited for A–C cups
  • M: best suited for B–D cups
  • L: best suited for C–E cups
  • XL–XXL: best suited for D–F+ cups

Fit may vary depending on how you prefer your coverage. For less coverage, size down. For more coverage or support, size up.


Structured Styled Tops & One-Piece Sizing

Styles with more structure and less adjustability—such as underwire or fixed panel designs—fit closer to traditional sizing.

As a general guide:

  • XS: best suited for A–B cups
  • S: best suited for B–C cups
  • M: best suited for C–D cups
  • L: best suited for D–E cups
  • XL: best suited for E–F cups
  • XXL: best suited for F+ cups

If you are between sizes or have a fuller bust, we recommend sizing up for the most comfortable fit.
