Our US size comparisons are approximate. The marked size is the size printed on the original label; check the item’s current measurements when judging fit.

Luxury garments may have been tailored for a previous owner. Fit can also vary by designer, collection and era—including when a new creative director changes a house’s proportions. A current chart may not describe an older piece.

Conversions are a starting point. Compare measurements with a similar item that fits you well.
