Who can forget Alicia Silverstone's iconic portrayal of Cher in cult classic "Clueless?" Silverstone's performance — and outfits throughout the film — have stood the test of the time.

Before "Clueless," Silverstone was known for her appearance in the Aerosmith music video for "Cryin'" when she was 16, and her role in "The Crush," for which she won the 1994 MTV Movie Award for Best Breakthrough Performance.

Since then, she's best known as an outspoken environmentalist, vegan, and animal rights activist. She's published a vegan cookbook, "The Kind Diet," and cofounded a line of organic herbals.
