Trendy Twins! Mary-Kate & Ashley Olsen Through the Years

Look back at how the stylish sisters went from acting on 'Full House' to ruling the runway

When Mary-Kate and Ashley Olsen stepped into the Hollywood scene at the young age of 9 months, they quickly became America's favorite darling duo. From TV shows and movies to books and fashion lines, the Olsen twins grew up right before our eyes -- building an empire that made them household names.

The sisters found their true calling when they produced the critically acclaimed lines, The Row, and Elizabeth and James, leaving their acting career behind. As the blonde beauties turn 27 on Thursday (wow!), see their transition from adorable actresses to fashion icons.

The pint-sized cuties may look like average five-year-old twins, but Mary-Kate and Ashley have been in front of the camera since they were only nine months old! The talented tots shared the career-defining role of Michelle Tanner on Full House for eight seasons.

The Olsen phenomenon has officially started! By 1993, Mary-Kate and Ashley released their first musical album, Brother for Sale, and starred in their first of many TV movies, To Grandmother's House We Go.

When one door closes, another one opens! After the series finale of Full House, the twins made their big-screen debut in It Takes Two. Starring alongside Steve Guttenberg and Kristie Alley, the twins helped bring in $19 million in ticket sales, while banking $1.6 million for themselves. Not too shabby!

Age 12

The Olsen twins smiled for the camera at the signing of their children's mystery book series, The Adventures of Mary-Kate and Ashley. They also returned to the small screen for the sitcom Two of a Kind, which only lasted one season.

They may be down, but they are not out! The blonde beauties continued their acting career by starring in the TV movies Passport to Paris and Switching Goals.

Age 15

Actresses turned fashion designers! Mary-Kate and Ashley launched their first clothing line for teen girls. But don't worry, the twins didn't give up on acting yet. They starred into another small-screen sitcom, So Little Time. Although the series lasted only one season, it earned Mary-Kate a Daytime Emmy nomination.

Age 17

For the second time, Mary-Kate and Ashley made an appearance on the big screen in the 2004 film, New York Minute. Unfortunately, the movie received harsh reviews and even worse ticket sales.

Age 18

By 2004, the Olsen twins received a star on Hollywood's Walk of Fame, graduated from high school, and became co-presidents of their multi-billion dollar empire, Dualstar. Mary-Kate's frail-looking figure on the Hollywood Walk of Fame sparked rumors of an eating disorder. The actress later checked into rehab for anorexia.

The sisters were seen less on the screen -- and more on the runway! The darling duo followed their true calling by launching a fashion line called The Row.

Just one year later, the blonde bombshells released another, more affordable, clothing line called Elizabeth and James.

Although they may look the same, they have their own unique styles. Ashley opts for a more clean cut and conservative look, while Mary-Kate flaunts a boho "homeless" look. The trendsetters were rewarded for their fashion with the style icon award at the Elle Style Awards.

Mary-Kate and Ashley were once again praised for their fashion when they took home the biggest prize of the CFDA awards! They were selected as the country's top women's wear designers for The Row. The trendy twins beat out tough competitors like Marc Jacobs and and Lazaro Hernandez. Unfortunately, this was also the year the twins announced their departure from acting (sigh).

From acting and designing, to health issues and tabloid drama, Mary-Kate and Ashley have always stood side by side through it all. We can't wait to see what they have in store for the fashion world next!
