Hundreds of people bared their briefs for London's annual ‘No Trousers Tube Ride’ last Sunday.

Trouserless passengers took to the Tube as part of the annual ‘No Pants Subway Ride’ - a global event that began in New York in 2002. This year's event was the first since the pandemic began and was the group's first trip on the Elizabeth line.

Attendees set off in winter warmers before splitting up to strip off in stations across the capital. Participants paraded across the concourse at Paddington, used ticket machines and escalators at stations without trousers, and rode the Elizabeth line half-suited and booted.

Taking place every year since 2009 (barring lockdown when it was on hiatus), the bizarre tradition started by a group known as Improv Everywhere. Organisers The Stiff Upper Lip Society said: “The aim of the event is to make people laugh and have fun," as people were encouraged to wear fun underwear, but nothing that might offend people.

During the tradition, hundreds of people headed to public transport fully-clothed, before then stripping down to their pants, as they shock fellow tube riders by their brazenness, whilst appearing blasé about the whole thing. More than 60 cities around the world now take part, including Berlin, Lisbon, Tokyo, and Toronto.
