Roll your sleeves up and dig into Guerrisol’s never-ending racks of second-hand clothes. A lot of it is tat, but every so often (and often enough for Guerrisol to be the most popular shop of its kind in Paris) you find a gem. It’s particularly good for blokes in need of a suit with all sorts of styles and colours. And the ladies’ shoe section often has a wide selection. Just wash before you wear: As your nostrils will tell you on the way in, Guerrisol smells like Eau de Charity Shop.
