纽约“无裤日” 乘客光腿乘车很“淡定”

At 3 pm sharp, subway riders at six separate meeting points across the city, boarded predetermined subway cars, engaging in typically unassuming behavior like reading a magazine or staring off into space.

But as soon as the doors shut at the stop before they were due to get off, participants were instructed to stand up, shed their skirts and pants (trousers), which were to be secreted into backpacks, and briefcases.

"If anyone asks you why you've removed your pants, tell them that they were 'getting uncomfortable'" instructions to emailed participants said.

Once they exited the train, the commuters stood for a while on the subway platform pantless, providing maximum shock effect to their stunned fellow riders.

Many participants donned festive underwear for the occasion, from polka dot bloomers to basic striped boxers, adding another a measure of frivolity to the unusual yearly happening, which also is staged in some 50 other cities in two dozen countries around the world.
