But unfortunately it revealed the actress' rather dimpled thighs as she arrived for brunch at a Hollywood restaurant.
Wearing a pair of unflattering blue seventies style shorts, and a t-shirt that read 'Let's go bite some butts', the 22-year-old actress looked more suited for a workout than lunch at restaurant La Scala, in Beverly Hills.

But despite her sporty attire, the slender 22-year-old's extremely pale thighs already appear to have some issues with cellulite.
Former O.C. star Mischa appears to have gained some weight since leaving the show which made her famous.
The packet of cigarettes may provide a clue as to why the young actress should be blighted by the stubborn fat, which affects many women, despite her youthful age.
Smoking is one of the toxic habits that contribute to the emergence of cellulite.

Mischa was meeting up with pals including regular Lindsay Lohan sparring partner, DJ Samantha Ronson, at the popular dining spot.
However, her dimply thighs haven't stopped her from baring all on screen in a new film.
Apparently, the London-born actress Mischa Barton had bared all in an upcoming Richard Attenborough directed movie Closing The Ring.
Mischa told The News of the World: "You do see me topless in the film and I did let Richard Attenborough get a brief behind shot as well."
Last month the actress learned she will face four charges as a result of her arrest for driving under the influence of drink and drugs.

Barton - who played television beauty Marissa Cooper in The O.C. - has been charged with possession of marijuana, driving under the influence, driving without a licence and driving with a blood alcohol level above the legal limit.
The charges made following the actress' December 27 arrest.
According to the police report at the time, Barton was pulled over in West Hollywood, California, when police saw her driving in the middle of two lanes and failing to signal when making a turn.
The star spent about seven hours in jail on the night of her arrest and was later released on $10,000 bail.
Barton accepted her responsibility for the arrest on American Idol host Ryan Seacrest's radio show after her release.
She said: "I don't know what to say about it except I'm not perfect."
