I'll agree with Superman (the costume that almost every superhero costume that followed copied in one way or another, and like Spider-Man it was unchanged for the movie), the Atom (Ray Palmer), Green Lantern (Hal Jordan), and Spider-Man. I'll add to the list Batman (as tweaked by Carmine Infantino in 1960's, in particular), the Angel (the red & white costume he had back in the 70s/80s) and Hawkman (original look and the 1990's Jan Duursema version, even if I wasn't crazy about the metal wings).
