History of National Wrong Trousers Day
National Wrong Trousers Day was first held in 1997 to support Bristol Children’s Hospital. The event was organized by The Grand Appeal and Aardman Animations, the creators of Wallace and Gromit. The idea was inspired by the animated short film The Wrong Trousers, in which a mischievous penguin uses robotic trousers to carry out a diamond heist.
The campaign began as a fundraising effort for one hospital and later expanded to support children’s hospitals and hospices across the UK.
