Joanna Lumley has launched London’s first ever Little Shwop of Horrors just in time for Halloween at Marks and Spencer’s Marble Arch store in London. The ‘Shwop’ gives the public the chance to pick-up their own terrifying outfits from cast-offs donated by celebs including Jessie J, Nadine Coyle, Naomi Harris, Jools Holland and Sophie Dahl. The shwop – in collaboration with Oxfam – also encourages old clothing donations from visitors and will be open until 9pm tonight (29.10.14).
