Much like Tony Stark and his never-ending array of Iron Man suits for every occasion, you too will want to keep your options open for the Con.
Have a few different costume possibilities for different genres, depending on the girls you like. Something superficially geeky for the more casual girls, something obscure and detailed for hardcore cosplayers and maybe something that shows off your ultra svelte comic-fanboy figure.
Don't forget the more stylish evening-wear, either. You'll need to be able to impress off-campus, too.
