When you say Berlin, you say vintage (second hand is also okay). I've never seen so many vintage stores and flea markets in one city.
As I'm currently on a budget, I find it a sport to find nice pieces in a pile of 'junk'. And yeah, its really a sport, the first time I went to Colours, one of the biggest vintage shops in Berlin I could only spend halve an hour max, so much choice, so many clothes, it made my head spin..
So my friend and I decided to go back there one morning, ready to attack all those clothing racks. We spend three (!) whole hours in Colours and came home with some nice and cheap goodies. I really loved some of the leather boots they sell, unfortunately, none of these in my size.. I'll just keep on coming back to see what's 'new'.
