Clothes Horses: Episode 7

It's been nine months since our last clothes inspired guessing game where Shane guessed Audrey Hepburn (from Breakfast at Tiffany's days). So, I've returned and the film is more recent although the setting is more distant. I think this is a simple one I've given you for the return (click to embiggen).

Clue: She's only just moved to a new "town". She's nervous.

Who is she and what movie is she in?
