Size Guide

All measurements are taken on the garment laid flat, in centimetres. Double the chest figure to get the full circumference. Allow 1–2 cm tolerance — these are cut-and-sew garments, not machined parts.

How our fits run

Tees and hoodies are cut relaxed with drop shoulders. Your usual size gives a loose fit; one size up gives a properly oversized one.
The shoulder figure is measured across the garment, so it reads much wider than your own shoulder width. That is the drop-shoulder cut, not an error.
Caps are one size with an adjustable strap.

Claude Minimal Tee and Claude Code Vintage Tee

These run from S to 4XL on a regular unisex fit rather than the oversized cut above. They fit true to size — size up if you want a looser look. Detailed flat measurements are not published for these two styles yet; if you are between sizes, ask us before ordering and we will check the specific garment for you.
