She is the ultimate arbiter of high fashion most at home on the runway front row.

But British Vogue editor Alexandra Shulman has chosen the more humble setting of a Primrose Hill charity shop to host a signing of her first novel.

The Mary Portas Living And Giving Save The Children shop, launched in 2010 by “queen of shops” Mary Portas, is hosting the event as part of its mission to revitalise the high street.

Krissy Marton, manager of the shop in Regent’s Park Road, said they are “really honoured” to welcome Alexandra.

She said: “The idea is that charity shops can be community hubs, when people walk in through the door it should be so much more than a shop.

“The concept is revolutionary, it is totally transforming what people expect from their charity shop.”

Alexandra will be signing copies of her book Can We Still Be friends? at the shop on Wednesday, June 27.

The shop also hosted a children’s fashion show to raise funds on Sunday (June 10), attended by volunteer and TV presenter Gail Porter.
