Size Guide

All Error451.store clothing is unisex by design — a clean, comfortable fit that avoids the usual fashion nonsense. Whether you wear it oversized or fitted, we recommend comparing against a shirt or hoodie you already like the feel of.

Measurements below are taken from flat garments (not body dimensions). Use a tape measure and compare against something you own. Each product has a size tolerance of ±3.8 cm, because humans and cotton aren’t exact.
