Reign Vintage started out in 2002 and really established themselves in the vintage fashion world, later opening two stores in London and Oxford. Handily, they have a decent, regularly updated online store, too, making it easier than ever to shop for second-hand treasures. They source a lot of their stock from Europe, and shoppers can expect to find fun logo sweatshirts and kitsch dresses mixed in with Gucci loafers and Versace blazers. Prices are fair – £25 or so for a pretty vintage shirt.
