Shihakushō

A is the standard Shinigami uniform worn by all members of the Gotei 13 as well as the Royal Guard.

Overview
The Shihakushō is composed of a white, a black , a black , a white hakama-himo, white , and. The black kosode has its owner's division insignia emblazoned on the inside. Lieutenants of the Gotei 13 sometimes wear an armband which carries their division symbol and its number, usually on their left arm. They are required to do this when they are summoned to a meeting, but apart from this, it is rarely compulsory.

Captains additionally wear a white over the usual black Shinigami clothes, with the number of their division on the back inside the Gotei 13 symbol (a rhombus). Some captain haori have long sleeves, while others do not. The color of the underside is division — or at least captain — specific, for every captain has a different color of it. The haori is meant to signify a captain's status, and Yamamoto was furious when Captains Kuchiki, Kyōraku and Zaraki lost theirs in battle and were acting indifferent about it.
