Grand Admiral uniform

The uniform worn by the Grand Admirals of the Galactic Empire was a variant of the Imperial military uniforms, originally designed by Moff Wilhuff Tarkin.

History
Some time before the Battle of Yavin, Grand Admiral Thrawn wore the uniform when he was tasked with defeating the early rebellion against the Galactic Empire, along with a black holster to carry his blaster pistol. On the contrary, approximately four years after the Battle of Yavin, Rae Sloane of the Imperial Navy still wore an Imperial gray jacket after she had attained the rank of Grand Admiral.

Design
Similar in cut to the standard Imperial uniform, the Grand Admiral uniform consisted double-breasted white tunic with a round collar and matching trousers, a pair of black boots, several code cylinders, a black belt and an identity disk placed on the belt buckle.

The uniform also featured a rank insignia plaque with twelve squares, three blue and three gold over trios of blue and red, which was also used by Grand Generals. While Tarkin and many military leaders believed that the use of medals and epaulets put more emphasis on status as opposed to duty, the Grand Admiral uniform had gold shoulder boards.

Behind the scenes
The rank of Grand Admiral, and the Grand Admiral uniform, were first appeared in the 1991 Legends novel Heir to the Empire, written by Timothy Zahn. The uniform was first pictured in the novel's cover, created by Tom Jung. At Star Wars Celebration London on July 16, 2016, it was revealed that both the title and the uniform will be introduced into canon with the releases of the third season of the animated series Star Wars Rebels, and the 2017 novel Thrawn, also written by Timothy Zahn.
