One way of dressing inappropriately in a foreign country is by not dressing up at all.
BERLIN – A naked American tourist raised eyebrows when he went for a walk through a German city and told police he thought this was acceptable behavior in Germany.
Apparently, nude sunbathing IS acceptable in public parks. However, walking around the city nude is a big no-no. (Hell, it’s a big no-no everywhere save for nude beaches and naturist playgrounds).
