One of America's best-loved sweethearts, Reese Witherspoon [1], turns 40 today. Reese captured the public's attention in late 90s thanks to films like Pleasantville, Cruel Intentions, and Election, and as Elle Woods in 2001's Legally Blonde, the actress skyrocketed into fame.

Since then, she's had an array of successful films including Walk the Line and more lately, Wild, as well as some equally impressive beauty looks to boot. In honor of Reese's birthday, we're taking a look back at her classic style.
