Shop like the French gentlemen do...at Arny's, 14 Rue de Sevres. Arny's is the home of the Forestiere jacket, an evolved version of the heavy corduroy peasant smocks that you'll find in the various Puce around the city and for exorbitant amounts in the second hand clothes shops around the Pompidou Centre. The Forestiere jacket is not for everyone as it is rather loose fitting (it looks best on the shorter, broader body) but the shop itself is beautiful and well worth a look and some of the accessories are just beautiful.
