Anyone know a good Christmas gift for "her" for $300?

I'm looking to get my girlfriend who's into having expensive stuff (what girl isn't). The thing is she has the latest things out right now from Ugg boots to Ipad. She could use some accessories but I can't find anything good for $300. Either I need to spend more to like $600 (when I'm trying to save for a certain "ring") or I can't find the certain high brand that looks good and that she'll like. The only thing I can come up with are some good pair of brand name sungles like Chanel or Dior. Any suggestions? Thanks!!!
