normal clothing just like you and me unless your a hippy or a emo
I wouldn’t get caught dead wearing big white name brand “athletic” shoes in Germany! Overall, in Fall and Winter, I’ve observed that Germans wear muted fabrics – lots of blacks, navies, browns, especially in footwear. One can see Americans a kilometer away – jeans, sloppy t-shirts and big white tennis shoes. Yes, we do stand out in this garb! Wear leather shoes and somber colors and you’ll fit right in during the colder months. Avoid dumb baggy logo t-shirts also – I’ve not seen Germans wearing them either.
