Had we even tried to sneak into the Marc Jacobs party last night, we definitely wouldn't have been able to muster a costume elaborate and erotic enough to blend in. While Marc's own costume was only skanky metaphorically, pretty much everyone else flexed the boundaries of taste, sexiness, and the definition of the word "costume." The theme was Arabian Nights, and Marc went as "Camel Toe." His boyfriend, Jason Preston, went as Abu, the adorable little monkey from Aladdin.
