The Girl Scout sash is designed to lay on the right shoulder, go around the body, with the bottom of the sash on the left side of the body. The Girl Scout vest is designed so that it is worn by inserting both arms with an opening on the front. Placement of the insignia and awards is different on each. When wearing the Girl Scout sash, the pin tab with the membership pin and the WAGGGS pin is worn on the left side of the shirt rather than being on the sash. See related links for illustrations of both the Girl Scout sash and the Girl Scout vest.

Girl Scouts of the USA (GSUSA) used to have a pattern and material that you could buy to sew your own sash. However, they discontinued selling them many years ago.
