How to measure⌄
Neck — around the base where a collar sits, with one finger of room.
Chest — the fullest part, under the arms, tape level across the back.
Waist — at the navel, relaxed — not pulled in.
Wear a thin shirt, keep the tape snug but not tight, and don't hold your breath.

Your build
Two men at the same height and weight can be shaped differently. This fine-tunes the waist and which cut suits you — it shapes the fit more than the size.
Sizing you from height & weight — the quickest way.

Shirts you can wear
Based on your fit and size
Full measurements ⌄
These are the shirt's finished measurements — the garment itself, not your body. The easiest way to use them: match against a shirt you already own that fits the way you like. Chest and waist are measured all the way around; collar is your neck size.
Reviews
Trusted by 400,000+ customers.
“This beautiful Navy shirt really upped my sartorial game. The feel is of a soft fabric with the build quality of a tank. As a recovering bespoke shirt buyer, these easily rank with the best that Budds and Charvet make.”
“Wore it to a wedding. It looked better than a custom made one I bought.”
Inc. Magazine
“A menswear company created a futuristic shirt campaign and developed a cult following in the U.S., U.K., and Australia.”
