If you go to Paris go and shop at
Kiliwatch in a very cool disctrict close to the Etienne Marcel metro stop.... The area is packed with streetwear brands and boutiques and the street in which there is also Kiliwatch is a must see; Rue Tiquetonne. The shop has a unique style offering vintage clothes (and a hell lot of them seriously) and brands like Numph, Cheap Monday and April 77. But hey even if you don't go to Paris in these days check their website since it is another must see.
