I won't call here underrated because she won an Oscar for Dracula, I'm just rather saddened that she did most of her work only with Tarsem and didn't get to shine on any real prestige picture other than Dracula. The way that we know of Jim Henson, Ray Harryhausen, Stan Winston, and Rick Baker - I think she was that level.
A lil video about her work Shows some of her work on the never-finished Spider-Man broadway musical

15min documentary "The Costumes are the Sets" about her work on Dracula. Interesting how she wasn't a costume designer until Francis Ford Coppola asked her to. She had done the Japanese poster for Apocalypse Now.
While we can adore her work in the many movies she worked on, I can't help but wonder what could've been if she had worked on other big movies like Crouching Tiger, Avatar, or even some of the factions in the Hobbit/LOTR movies.
