Brainstorming for Creative Gallery

I love the detournement ideas--I could do a collage in which the articles of designer brand clothing on Polyvore go back to other countries and working conditions, or a comment on how the look of these items reflect body types that aren't appropriate or healthy. The best idea to me however would be to show that no matter how creative the collage its still an advertisement for something else and is constrained by the limits of what companies have created and that lesser known companies aren't featured as options for artwork.
