In the early 1990s was when the Girl Scout started to use corporate navy blue in the adult uniforms. It is very evident on this page here. Suprisingly around this time I knew of many leaders that wore the green "Bill Blass" dress, often, sewn at home. It was a much cheaper alternative. Or more common, leaders were still wearing the logo print blouses and the green slacks or wrap-around skirt. This is a page from the 1993 Girl Scout Catalog.
