I like Anne Hathaway's style, too! She also had a great magazine shot recently, was it in Vogue or Vanity Fair? Loved it.
I also like Michelle Williams (cutest casual looks), Cate Blanchett, Penelope Cruz (SWOOOOON), Rhianna, Gwen Stefani, Katie Holmes for their sense of style.
Reese Witherspoon has a good easy smart casual style. Jennifer Aniston is very polished but a little too "safe" for my taste, I'd love for her to experiment a bit more and use more color in her wardrobe. And Angelina Jolie is even more "color safe" (too much grey and black for my taste) and I'd love for her to go more tailored vs. flowing. But she sure is gorgeous.
