What I would do is think about the concept you want to do. How do you want to steampunk Marilyn Monroe? Is she a singer in a vaudeville hall, a gold digging lady with a voice, A wind up singing doll? If you start with a strong idea you will end up with something that looks lots better than if you spangled it with gears like buck shot.
I totally agree with this. Sticking on random gears, clock faces, and goggles really cheapens a steampunk look. It's become so typical that it really makes it "costumey" and you don't want that.
I like the thought of getting a good idea of what you want her to be, then figure out how you can steampunk it without ruining the integrity of both the costume and Marilyn Monroe in general.
