Coat sleeve

A structured set-in sleeve tailored for outerwear coats—the two-piece or plain set-in form with sleeve-head ease on wool and cashmere, distinct from shirt sleeve lightness and from raglan casual knits.

How to recognize it

Coat sleeve shows a set-in armhole with structured cap and often two-piece tailoring on outerwear.

Set-in sleeve is the general construction. Two-piece sleeve splits upper and under panels on suiting.

Origin and history

Sleeve tailoring distinguishes coat sleeves from shirt and knit forms.[1] Coat articles describe set-in sleeves on wool overcoats and peacoats.[2] Tailoring covers sleeve-head ease on wool jackets.[3] Museum dress-shirt photography documents set-in cuff cousins on cotton.[4]

Coat sleeves need pitch and ease for arm lift.[3] Coat differs from raglan diagonal seam.[1] Contrast with unlined casual finish.[2]

Today coat sleeve appears on wool overcoats, trench coats, and blazers in wool and cashmere.[1][2] Two-piece coat sleeve improves arm bend.[3] When outerwear uses structured set-in tailoring—coat sleeve applies.[2]

Where it is used

Wool overcoats, trench coats, blazers, and tailored outerwear.[2]
