The London Underwear

When temperatures in London dip below freezing, it's generally seen as time to button up, throw on a scarf and pop on some extra layers. It is NOT recognised as a good time to take off your trousers. But this Sunday, that's what will be happening on the inaugural No Trousers Underground Ride.

Started as the No Pants Subway Ride in New York in 2002, the aim is to act nonchalant. as if you've simply forgotten to wear trousers. From the instructions:

"When you enter, act as you normally would. You do not know any of the other pantless riders. If questioned, tell folks that you “forgot to wear trousers” and yes you are “a little cold.” Insist that it is a coincidence that others also forgot their trousers. Be nice and friendly and normal.

You can wear fun underwear if you like, but nothing that screams out, “I wore this because I’m doing a silly stunt.” Wear two pairs of underwear if it makes you feel more comfortable. Don’t wear a thong or anything else that might offend people. Our aim is to make people laugh, not piss them off."

3.00 p.m., Trafalgar Square. See you there.
