This is the beacon of fashion movies.
Anne Hathaway plays a young woman who gets a job as a assistant secretary for Meryl Streep who plays the owner of a famous fashion magazine called Runway (vogue rings the bell here).
It's a great story about how fashion is really more than fashion, since it is art that we actually wear, and how we are ignorant to the fact that we are deeply affected by fashion magazines even if we try to avoid fashion.
Also about having a impossible boss. Meryl Streep is nothing short than marvelous in this movie.
