In The Social Network, what does Mark Zuckerberg say he is wearing?

In The Social Network, Mark Zuckerberg says he is wearing “a Harvard sweatshirt.”

The line appears during the opening conversation between Zuckerberg and Erica Albright, when she asks what he is wearing. His answer is deliberately literal and reveals his connection to Harvard University, where he is a student at the beginning of the film.

The exchange quickly becomes tense because Zuckerberg focuses on factual details while Erica evaluates his behavior and ambition. That contrast introduces the film’s portrait of a socially awkward, intensely competitive young programmer. The clothing detail is minor, but it helps anchor the scene in Harvard’s campus culture.

The Social Network was released in 2010 and dramatizes the creation of Facebook and the lawsuits that followed. Jesse Eisenberg plays Zuckerberg, while Aaron Sorkin wrote the screenplay. The film is based partly on Ben Mezrich’s book The Accidental Billionaires, so its dialogue is a dramatized interpretation rather than a complete documentary transcript.
