Haori

A haori (羽織) is a traditional Japanese jacket worn over a kimono.

Resembling a shortened kimono with no overlapping front panels (okumi), the haori typically features a thinner collar than that of a kimono, and is sewn with the addition of two thin, triangular panels at either side seam.

During the Edo period, economic growth within the wealthy but low-status merchant classes resulted in an excess of disposable income, much of which was spent on clothing.

It was during this period that, due to various edicts on dress mandated by the ruling classes, merchant-class Japanese men began to wear haori with plain external designs and lavishly-decorated linings, a trend still seen in men's haori today.
