These girls hired me for making some costumes and they were trying to make a little parody to "Charlie's Angels" name, so that's why we uniformed their outfits to be "The Office's angels", and, as they were making a Halloween costume, I made them the look of Dark Angels.
I have a "How to" of their wings, and the result is the one shown in the pictures, sorry I cannot give you a complete picture, you know how is this of taking care of privacy =S.
