Sexual Content (Pause): Some sexual allusions, Andy has sex with a guy.
Violence (Not an Issue): Emily is hit by a cab (at first played for comedy, but we later see her in the hospital).
Language (Pause): Many uses of "s*it", a few uses of "hell" and "ass" (1 used with "-hole"), and 1 use each of "crap" and "bullocks" (a British swear).
Social Behavior (Not an Issue): Lots of lying and decieving, but Andy is able to maintain her morality (for the most part, anyway).
Commercialism (Pause): Seeing as this movie is all about fashion, there are lots of brand names dropped (such as Prada), Starbucks is mentioned a few times, as is Harry Potter.
Drug/Alcohol/Tobacco (Pause): Social drinking, except for one instance where Andy gets drunk.
