Reese Witherspoon's Style Evolution (PHOTOS)

Best known for her roles as over-achieving high schooler Tracy Flick in the film adaptation of "Election" and as pink-clad law student Elle Woods in "Legally Blonde," Reese Witherspoon, who just starred in "This Means War," is one of America's most stylish sweethearts.

The chic actress, who married her second husband, Jim Toth, in June 2011, may be pregnant again, according to multiple sources. Witherspoon is already the mother of two children, Ava and Deacon, from her prior marriage to her "Cruel Intentions" co-star Ryan Phillippe.

Off camera, Witherspoon's mommy style is feminine, yet low-key, but the Hollywood A-lister still turns up the heat on the red carpet. Favoring fashionable, sexy mini dresses, we are never left disappointed.

In addition to a possible pregnancy, Witherspoon has a lot to celebrate these days: her 36th birthday is on March 22. So, we've decided to take a look back at her star style. Which look do you think is the most glamorous?
