Chicago commuters sheds trousers for No Pants Subway Ride

The 10th annual 'No Pants Subway Ride' saw commuters across the US shed their clothes from the waist down on Sunday.

These travellers on Chicago's "L" subway trains discarded their trousers as part of the event.

The annual event began in New York City in 2002 and takes place in about 50 other cities in two dozen countries around the world.
