Sandra Bullock Style Evolution: From Baggy Jeans To Glamorous Gowns (PHOTOS)

Sandra Bullock has graced the red carpet for nearly two decades and always clutching the best accessory: Man candy. With co-stars such as Keanu Reeves, Bradley Cooper and Ryan Reynolds, and boyfriends like Matthew McConaughey and Ryan Gosling, the former Mrs. Jesse James has shown off many of Hollywood's hottest men.

Maybe it's her "one of the guys" on-screen demeanor (think "Speed" tomboy and "Miss Congeniality" tough girl), but hunks aren't the only thing Bullock has switched up over the years. We've seen the brunette beauty experiment with various hairstyles--from bobs and bangs to buns. And fans swooned once she ditched her baggy denim for glamorous gowns, a major change in her wardrobe that has remained consistently fabulous.

To celebrate Sandra Bullock's 48th birthday on Thursday (July 26th), we're taking a look back at the Oscar-winning actress' style over the years. Vote on all her looks in the slideshow below.
