The maritime charity Seafarers UK is asking people to wear striped clothing for the day to raise money for maritime workers and their families who are suffering hardship.
The Get Stripey fundraising initiative will take place on Friday 16 May, and people who take part are being asked to donate £1 for wearing striped clothing.
The charity has sent a mailshot, supported by the maritime industry newspaper Lloyd’s List and the website Lloyd’s List Intelligence, to about 5,000 maritime businesses, calling on them to take part in the initiative.
A spokesman for the charity said it hadn’t set a fundraising target for the campaign, which is running for the first time this year, but said it hoped to secure a "large income" from the initiative.
He said that it received grant applications of between £4m and £5m a year, but was currently able to award grants totalling only £2.5m a year. He said that it hoped the initiative would help it to meet more of the demand.
Seafarers UK supports those in need from the merchant navy, fishing fleets, the Royal Navy and the Royal Marines.
Nigel Shattock, director of fundraising and communications at Seafarers UK, said in a statement: "Get Stripey is an incredibly simple and fun idea, and we really hope that staff at all levels and in any role will want to get involved, as little or as much as they can.
"People can come to work dressed in a smart stripey top, a pair of stripey socks or perhaps a very loud stripey skirt or tie. They might want to be subtle and just paint stripes on their nails, or make more effort and even bake something stripey to sell. Basically, anything stripey goes, even hair."
