The pop up, located on the second floor of the London store near brands such as Miu Miu and Gucci, will be open for four weeks, with prices ranging from £3 for a pair of sparkly earrings to £450 for a vintage Jean-Paul Gaultier suit. Oxfam, which was founded in Oxford and is now headquartered in Nairobi, is an umbrella group for a variety of charities seeking to alleviate global poverty. It is one of the largest retailers in the U.K. through its network of charity shops selling clothing, books and vinyl records. The shop at Selfridges showcases a mix of accessories – including a boater hat and cool, worn-in cowboy boots, books and jewellery – and clothing such as a beaded, corseted dress, a printed A-line coat, a navy men’s jacket with gold military piping and an Ossie Clark dress.

The shop is part of Oxfam’s annual Second-hand September campaign, and also speaks to the new commitments made by Selfridges as part of its Project Earth sustainability initiative. Selfridges said that customers will be able to try on the clothes and accessories, which will be subject to the same hygiene standards as new items at the store. Items tried on but not purchased at Selfridges are cleaned and quarantined for 48 hours.
