During the New York Anime Festival, it was Santa-Con that took place in Manhattan, which hundreds of Santas came together. But this gathering is a little different, instead of Santas walking around, it was “No Pants Day,” that took place on Saturday. Hundreds of people came together at a Subway station by wearing no pants. According to Improv Everywhere, the organization that held the event, said there was an estimated 900 participants in the event.

“It was basically like a sci-fi convention with people wearing costumes, but instead, it was people wearing no pants.”

The group splits into three different subway trains and took the subway from downtown Manhattan to Union Square.
