Diesel founder Renzo Rosso is glad to be back in the German capital.

Rosso founded Diesel in 19-78 and the brand has since become part of global youth culture.

Rosso brought along his two sons Stefano and Andrea who happliy showed off their very own style mix made up of camouflage trousers, anoraks and hats.

Diesel´s new campaign for 2010 is themed "Be Stupid".

Rosso said "The new image is about how stupid people are the people who have the power to do brave things."

The fashion showed on the runway stayed true to the new motto.

"Brave" combinations and bold colours brought back the Eighties, gothic is back and so are neon colours. Studs and chains round off the slighty punky feel.

Diesel also has a stand at the Bread & Butter fair at Berlin´s historic airport Tempelhof.
