If you're dressing up like a celebrity tomorrow, finding a complementary fragrance isn't too difficult. Anyone in a Seven Year Itch white dress should wear a splash of Chanel No. 5 (Marilyn's signature scent). Pop-star impersonators need look no further than the star's namesake scent: Lady Gaga's Fame (the black claw-topped scent above), Katy Perry's Killer Queen or Purr (depending on the Perry era you're channeling), or Nicki Minaj's Minajesty. As for all those Miley Cyrus costumes? A perfume with cannabis notes should do the trick--we like Fresh Cannabis Rose.

If you're going for the undead look, stay away from crowd-clearing notes of guts and gore and opt instead for Demeter's Zombie (mossy, forest-like notes) or Dirt, which smells just like the name suggests but in the best way possible (more grassy childhood backyard than filth). Personally, I like to get a little meta with my costume scent choices. Think Marc Jacobs's Daisy for a Great Gatsby getup (at right, above), or Elizabeth Taylor's White Diamonds for Cleopatra (center, above). I can make a multitiered pop-culture statement just by walking into a room--even if I'm the only one who notices.
