Size guide · Frippy

Skip to content

Letter sizes like XS, S, M, L and XL are the same in every system, so they’re never converted.

≈ means approximate: these systems don’t line up exactly, so check the measurements in the listing or ask the seller.

A dash means there’s no matching size in that system.
