Mary-Kate and Ashley Olsen have always held a special place in our hearts -- first for their role as Michelle Tanner on Full House, and now, as full-fledged fashion designers for lines The Row and Elizabeth & James.

Though it's hard to imagine a time when the twins weren't in the tabloids for their bold sense of fashion, the dynamic duo, as they are so often referred to, once starred in some of our most beloved children's movies. It Takes Two, anyone? Passport to Paris? Back in the day, the Olsen twins were synonymous with seriously entertaining home video for girls of all ages.

These days, the newly turned 27-year-olds have made solid names for themselves in the fashion industry, as trend-setters both on the runway with The Row and on the streets with their unique and daring personal styles.
