Mary-Kate Olsen is an American actress, fashion designer, producer, author, and businesswoman.
Along with her fraternal twin sister Ashley Olsen, Mary-Kate initially gained fame at nine months old when they portrayed Michelle Tanner on Full House during the series entire 1987–95 run.
In the early 1990s, she and Ashley established a company, Dualstar, which produced a long string of TV movies and direct-to-video releases featuring the girls. The Olsens continued to release direct-to-video films up to the early 2000s, along with starring in the 1995 feature film It Takes Two. In 1997, the Olsen twins guest starred in an episode of Sister, Sister, alongside fellow twin actresses Tia Mowry and Tamera Mowry. After Full House, the sisters starred in two other sitcoms (Two of a Kind and So Little Time) and an animated series (Mary-Kate and Ashley in Action!). The former lasted one season while the latter ran for two seasons. These ventures, combined with an array of licensing deals for their names and likenesses, made Olsen wealthy at a young age. In 2004, Olsen's wealth was estimated at $137 million.
Olsen and her sister became co-presidents of Dualstar upon their eighteenth birthday. Olsen's first solo acting appearance was a DVD only scene in the movie Factory Girl, released in December 2006. In 2007, the sisters said that if they became involved in movies together again it would be as producers. Olsen had a recurring role on Weeds as 'Tara Lindman.' In 2008, she appeared The Wackness as 'Union'. In 2008 Olsen also made a guest appearance on the ABC comedy Samantha Who? as a self-destructive girl that Samantha tries to help. Olsen appeared in the motion picture adaption of the Alex Flinn novel Beastly.Olsen at the premiere of the Woody Allen film Whatever Works at the 2009 Tribeca Film Festival.
In March of 2012, both Mary-Kate and Ashley indicated their interest to retire as actresses in order to focus on their careers in fashion. Mary-Kate and Ashley felt that their futures were in fashion, and not in acting. They discussed wanting to open a store as one of their future fashion-based endeavors.
Following a high volume of public interest in their fashion choices, the sisters began work in collaboration on a string of fashion lines available to the public. Starting as young girls, the Olsen twins started a clothing line in Wal-Mart stores across America for girls ages 4 to 14 as well as a beauty line called "Mary-Kate and Ashley: Real fashion for real girls".
In 2006, in an attempt to gain credibility in the fashion industry after their association with Wal-Mart tarnished their reputations, they were tapped as the faces of the upscale fashion line Badgley Mischka.
As adults, the Olsen twins have devoted much of their attention to the world of fashion. They head a couture fashion label, "The Row," as well as "Elizabeth and James", "Olsenboye", and "StyleMint"retail collections. Mary-Kate's sometimes controversial fashion choices have often found her on both the best and worst dressed fashion lists, particularly for her decision to wear fur.Mary-Kate and Ashley designed an Olsenboye Change Purse in 2011 and donated the money to "Pennies From Heaven".
In 2011, Mary-Kate and Ashley teamed up with TOMS Shoes to design footwear for kids without shoes in more than 20 countries worldwide. Mary-Kate and Ashley are now the creative directors for Superga.
