Vintage International Size Guide & Measurements

International Size Guide

This is an international size guide to help you find your best fit. Because we sell vintage and secondhand clothing, sizing can vary significantly between brands, decades, and countries of origin.

Always check the item's actual measurements when available, and when in doubt, review the measurements in our images. If you'd like a specific measurement, please reach out.

Every measurement here is taken with the garment laid flat and measured straight across with a ruler — never measured around the body. The easiest way to find your size is to measure a piece you already own that fits you well, laid flat, and compare.

Units:

How to measure: Lay a top that fits you flat and smooth out wrinkles. Measure straight across from armpit to armpit. Compare to the chart below.
