Passengers strip down to pants for No Trousers Tube Ride
The event is marking its 10th anniversary.
Hundreds of people have stripped off their trousers to take a half-naked trip on the London Underground.
Crowds met outside the National Gallery in Trafalgar Square for the 10th annual No Trousers Tube Ride before heading underground where they boarded trains on different Tube lines across the capital.
Regular Sunday passengers were left bewildered as men and women sat in their brightly-coloured underwear talking or reading, or taking pictures of each other.
Other groups set off for London landmarks, including one heading to Parliament.
Tessa, 24, from London, said: “We read about it and thought it sounded hilarious. I wasn’t nervous about it.
“I quite like the sentiment behind it, instead of a stiff upper lip it’s having a bit of a laugh.”
Matilda, 22, added: “I did especially pick out my pants, you have got to pick out a nice opaque one. You don’t want to give too much of a spectacle.”
The London event was organised by the Stiff Upper Lip Society, which asked participants to “avoid thongs/budgie-smugglers/anything see-through though, as we aim to amuse, not offend, fellow Underground users”.
One of the organisers, Farhan Rasheed, said there was not really an aim to the event, it was just a bit of fun.
“People just have fun doing it, it’s a bit of a nonsense day out.
“You very rarely get people who are offended. It’s London and London is used to this stuff, they take it in their stride and get back to their book.”
