Size Guide

Fit is one of the most important decisions in choosing a garment, so we've kept our sizing as straightforward as possible.

Each product page includes specific measurements for that style, since fit can vary slightly between silhouettes. A relaxed shirt and a tailored trouser won't follow identical logic. Below, you'll find general size charts by category, along with guidance on how to measure yourself at home.

If you're between sizes or unsure which to choose, write to us at opnfold@gmail.com with your measurements. We're glad to help you choose before you buy, rather than after.
