This vintage jacket was made in the 1930s for United Costumers, Inc., an early Hollywood costume house catering to the film industry.  This one is an elevator operator’s uniform.  It is double breasted, with metal buttons and a black collar.  There is black sleeve piping and the remains of stitching from where a diamond shaped patch was removed from the sleeve.
