Dianna Agron wraps a pretty red ribbon belt around a Prada dress as she arrives at the 2011 FOX TCA Winter Party held at Villa Sorriso in Pasadena, Calif., on Tuesday night (January 11).

The 24-year-old actress, who’s new film I Am Number Four opens next month, opened up to JustJaredJr.com about the fashion of her character, Sarah.

Dianna dished, “Marie-Sylvie, the wardrobe designer for this film, we kind of went through a couple different bouts of is she this type of girl or is she this type of girl and Marie’s amazing. We kind of came up with the idea that she lives in a smaller town and is more fashion forward because she is artsy and has the internet and has dreams of going elsewhere whether it be New York, Paris…somewhere where she can be creative and kind of further her aspirations of being a photographer. So yeah she’s kind of got that Parisian vibe to her. There’s a lot of berets and cardigans and just really fun young, youthful type clothes.”
