Suggesting something from the 90s, especially for Halloween, can be a little tricky because most of Halloween's staples are from this decade. The Sleepy Hollow, Chucky, Freddy's Dead: The Final Nightmare, Halloween: The Curse of Michael Myers, Mary Shelley's Frankenstein, and many more movies I can suggest you facsimile the looks but it is really up to you what sort of costume do you want because not everyone goes with the spooky stuff for the Halloween right! Or was I the only one who usually goes for the Scarlet Witch Coat featured kind of stuff from the movie?
