The Imperial Bridgecrew, or IC, is found on Imperial bases and on Imperial warships.  According the 501st Databank, "The Imperial Bridge Crew consists of Non-Commissioned officers assigned to the bridge of a starship. These crew members monitor and coordinate the overall functions of the ship." It's one of the simplest costumes to make, involving just sewing and a bit of leatherwork and readily available parts. It also can easily be used a base for TIE Pilot and Reserve TIE Pilot, Imperial Gunner, and Imperial Navy costumes.

The coveralls were racing uniforms in the original films, and the same pattern in different colors were used for several other costumes both Imperial (scanning crew), and Rebel (X-wing).

The boots are German WW2.

The hat has to be hand made, but there are patterns available.

The belt can be made with a belt blank, some stain, a buckle blank, and an imperial code disk. The code disk is available from several sources and is also used for the hat.
