Jackie O. loved her over-sized dark shades, Gwen Stefani can't give up her crimson pout and Michelle Obama never misses and opportunity to show off her toned arms in sleeveless frocks.

No matter how you slice it, when a woman finds something that works for their personality and their body type it's like finding the holy grail of fashion. Enter: Jennifer Aniston and her many mini dresses.

The star of "Horrible Bosses" recently took the red carpet in a sequined Balenciaga number that showed off her tan and toned legs -- a style the 40-year-old is very fond off. Since the early '90s the former "Friends" star has been rocking frocks with shorter hemlines. Favorites include LBD's and anything Valentino, but every once in a while Aniston will try something new -- like a revealing Vivienne Westwood dress.
