Try to avoid looking too much like an American. For example, Americans walk about in sneakers; Europeans wear shoes. Americans wear baseball caps emblazoned with the name of their favorite team; if you need to wear a hat, think about a European soccer team. And, it’s probably not a good idea to wear one of those T-shirts that indicate you are some kind party animal.
“American’s stick out like a sore thumb,” says Robert Diener, the founder of Getaroom.com and a travel expert. “This is a heads up to be more cautious.”
