A 46-year-old pub manager plans to wear a onesie every day for a year in an attempt to raise money for a cancer charity.
Chris Kiff, who runs the Nags Head in Aberystwyth, Ceredigion, hopes to raise thousands of pounds in donations for Macmillan Cancer Support.
Mr Kiff, who is nearly 6ft tall, says he will not return to his normal shirt and trousers until January 2015.
"I'm walking around in an adult babygro. It's completely against what I would normally wear," he said.
"But I've had friends and family who had to deal with cancer. I think the people at Macmillan are just great.
"And I wanted to do something to help that was a bit of fun.
"When I think of Macmillan, I think of comfort and support - and what could be more comfortable than a onesie?"
He added: "People have donated hundreds of pounds already."
Mr Kiff said he had one onesie - thought to be "unsie" in Welsh - when he decided to change his clothes.
But he said his collection was growing. "People are donating them, I've bought a few more, I've borrowed some," he said.
"Maybe I'll auction them off when I've finished."
