Funky clothing stores in Berlin

Hey everyone, I was wondering if anyone knows where to find cool rave / acid / party clothing in Berlin.. I'm thinking something like cyberdog or hexagon in London..

Also, are they are good flea markets, ie like camden town used to be anywhere in Berlin?

Thanx everyone.

A friend from NYC is looking to shop his new clothes line to some stores in Berlin. It's a hipster-y, funky line for young men/women.

I'm not a big shopper in general (and I live on the west side) so I don't really have a clue. I know there are some cool shops on Neue / Alte Schönhauserstrasse (near Hackescher Markt.)

Anyone know of any other clothes stores (or some specific locations of stores) that cater to this sort of crowd? I know there are tons of emerging and/or established young designers with shops in berlin but I just don't really know much about them.

Thanks for your help!

"hip" flea markets are boxhagener platz and mauerpark.
nice fashion stores are around wühlischstraße/kopernikusstraße/western simplonstraße in friedrichshain and (a bit more expensive) around U-Bahnhof Weinmeisterstraße/as said Neue/Alte schönhauser, and around Kastanienallee/Prenzlauer Berg.
Don't know about specific rave fashion stores though...
