The 'Best Song Ever' singers' personalized their one-piece playsuits with paint hand prints which were then snapped up by one lucky American fan at an auction as part of a charity event called 'OnePiece2WorkDay'.
The sale was organised by The CAW Foundation and fashion label OnePiece and encouraged thousands of people to wear the leisurewear to work.
Zayn Malik and Liam Payne’s fashionable donation pushed CAW founder, Rob Langley-Swain, towards his target of £50,000, raised in order to provide kids in deprived areas of the Midlands in England with arts, sports and cultural projects.
The charitable boyband have previously donated their star power to charity auctions, with devoted fans snapping up rare prizes.
Just last month, people were offered the chance to date band members Harry Styles and Liam Payne in order to raise money for cancer charity Trekstock.
One lucky bidder was able to snap up a five-star weekend in London's Carnaby Street, with spending money and a memorable evening with the two hearthrobs.
