Visitors to luxury London hotels may be interested in talking part in the Vintage Midnight Walk, taking place on September 10th.
The charity event is a unique fund raising opportunity for those interested in supporting the Richard House and St Joseph's hospices.
"We will be curling our hair and dusting off our fascinators and bowler hats for The Vintage Midnight Walk," explain the organisers.
"On the strike of midnight we will set off dressed in vintage clothes and descend on to the streets to walk ten miles in the name of two of east London's best loved hospices."
The formerly women-only event is now open to everybody, however men are also encouraged to get involved by volunteering as marshalls on the night to help.
Stylised around the 1920s to the 1940s, participants are encouraged to dress for the occasion.
"So, whether your style is more roaring twenties, swing starlet, or spirit of the blitz there's something for everyone!" the group explains.
However, planners do recommend that everyone wear trainers for the ten-mile stroll.
The route starts in Hackney and will pass through Bethnal Green, Whitechapel, The City, Old Street and Shoreditch, before returning to the stating point.
Registration for the event costs £15 per person, while the minimum sponsorship required is £100.
The Richard House Children's Hospice is the first one in London aimed at youngsters in a purpose-built building in Beckton.
"Our core purpose is to support children with life-threatening or life-limiting conditions," explains a spokesperson.
St Joseph's Hospice exists to help dangerously ill people "live life to the full", providing assistance, easing pain and bringing comfort and understanding to those in need.
