There's a new book in Germany about Star Wars called "Die Macht Mit Uns" (The Force With Us). It covers everything from toy collecting to prop creating. It also has a special chapter dedicated to what is apparently a "blossoming interest" in Slave Leia costuming by women fans. Er, ok.
Amazon has it if ya want: here.
I'm thinking an American version would look significantly different (anyone ever been to Comicon??!!!!)
