Fit Notes

— Our garments are cut with a relaxed, slightly oversized silhouette. If you prefer a closer fit, size down.
— Ribbed pieces have natural stretch — the measurements given are relaxed. They will conform to the body.
— Each product page includes a sizing note specific to that garment. Check there first.

Size and measurement guidance is included on each product page, alongside fit notes and, where available, the measurements of the model and the size shown.

For Mercer St. cotton socks, two sizes are offered: S/M (22–24.5 cm foot length) and M/L (25–27 cm foot length).
