Life imitates art for Dianna Agron as she steps out in Quinn Fabray's Glee finale dress

She's one of the most stylish schoolgirls at William McKinley High so it's no wonder Quinn Fabray's style in envied worldwide.

But it seems even Dianna Agron, who plays Quinn in hit US TV show Glee, is a fan of her character's quirky sense of fashion.

The 25-year-old actress was spotted out and about in Westwood, California, wearing the same patterned blue dress as Quinn sported in the Glee season finale earlier this year.

    

Dianna did style the outfit differently, however, removing the orange coat she wore with it in Glee and adding a different tan belt, while teaming it with flat pumps and a black shoulder bag.

The Glee star spoke recently about how she collaborated with stylists on Quinn's style, admitting she had taken inspiration from 1950 movie All About Eve.

She said: 'I watched All About Eve for Quinn’s look and attitude. All the Eve actresses wore fake eyelashes, so my character does too to add a little kick.'

Dianna, who appeared on People magazine's Most Beautiful list last year, also said it took her a while to get used to the beauty and grooming worlds.

She laughed: 'In high school I knew nothing about makeup and hair. I wore all the wrong colours and plucked my eyebrows too much.'

Meanwhile, it remains to be seen whether Dianna has a future on Glee after the third season.

        

Following the news that Lea Michele, Chris Colfer and Cory Monteith would not be returning to the show for season four, creator Ryan Murphy hinted the trio won't be the only stars to depart from William McKinley.

In his interview with The Hollywood Reporter, Murphy explained he had decided to let the stars graduate in order to bring a sense of realism to the show. 

He explained: 'You can keep them on the show for six years and people will criticise you for not being realistic, or you can be really true to life and say when they started the show they were very clearly sophomores and they should graduate at the end of their senior year.'

Murphy said that season three, which premieres on September 20, will see the cast focus on what lies ahead of them after school and beyond the New Directions glee club.
