What Is It With Leelee Sobieski?

What is it with Sobieski? Every movie I've seen her in she is wearing low cut shirts and her are hanging out of robes. Why is she casted this way in her movies? Is it because Hollywood conveys her as a beauty? Idk...this movie I am watching on Sleuth right now, In A Dark Place, I don't think she looks like a beauty because she has this washed out red hair. So what is up with her skimpy, slutty outfits she is always casted in???
