Size Guide

Everything you need to find your perfect fit.

Diagram showing where half chest and length are measured on a t-shirt

All top measurements are of the garment laid flat — not body measurements. The easiest way to check your size is to measure a t-shirt you already own and love the fit of.

Please note: as with all garment production, measurements can vary slightly piece to piece — typically within ±1.5cm of the figures below.
