To start with , I bought a Jean Jacket and an oversized winter jumper at "Kilo Shop" (http://kilo-shop.fr/) which is a vintage shop in Paris (Marais). It is such an original shop where every single item by the kilo.
Jumper-> 15 €
I bought a sport jacket and a checked shirt at "66 Vintage Story" (http://www.thevintedge.com/fr/friperies/187-vintage-66.html) which is a hudge and amazing shop in Chatelet. I loved it because there is a wide variety of different iteams and the shop is very well organized.
I bought an Abercrombie and Fitch jumper at the yard sell of my home city! :)
-> Jumper (2€)
I don't know if this short pants is a vintage piece of clothing, but since I found it behind my wardrobe in a summer camp, I'll include it in my post because I am pretty sure it is second-hand iteam !
And finally I found in Japan at Harajuku in a tiny shop called "Panama boy" (http://ameblo.jp/panamaused3) a pair of short pants and a dress made out of old frabrics !
