Sandra Bullock rose to fame with Speed in 1994, and we've since watched the leading lady blossom into a red-carpet fixture.

The laidback girl-next-door heroine of rom-coms like "Miss Congeniality" proved she has serious acting chops in The Blind Side, for which she took home an Oscar for best actress. And with that career milestone, her style has grown up too: The actress stunned in sophisticated creations by Vera Wang and Jenny Packham this year. And we can't wait to see what she wears to promote next year's Extremely Loud and Incredibly Close and Gravity.

In honor of Ms. Bullock's 47th birthday today, we present a look back at some of her memorable style moments.
