I am not a fashionista, hence the aim of this book is not to teach you how to appear "European." Actually, there is no "European" appearance. Like Americans, Europeans dress in many kinds of fashion, with country to country variations in the subtleties.
That said, lots of Europeans sport a casual t-shirt, shoes, and jeans wardrobe; fashions do often seem to be a little more "dressy," or "put together."
Thanks to globalization—that is, our shared shopping at comparable stores—there is really not much difference between what the average 25-year-old American wears and what their European counterparts wear.
This method will enable you to "blend in" enough that you are not taken for an American visitor from 100 yards away. If nothing else, this guidance will enable you to project a conventional European tourist image.
What Not To Wear Across Europe
If you wish to avoid seeming like a tourist, let's review some broad rules on what items you should not wear when visiting Europe.
Athletic Clothing
Especially in big cities, it is unusual to find Europeans sporting head-to--toe sports gear. So if you see a gathering of individuals sporting basketball shorts and t-shirts, you can be very sure you are looking at Americans. Sports jerseys follow the same rules.
Overtly Athletic Shoes
Europeans don sneakers, particularly stylish ones.
So, really, you are free to wear shoes in Europe! Given that you walk many kilometers every day, I advise you to 1,000% wear sneakers in Europe.
However, unless they are participating in an athletic event, you seldom find stylish Europeans sporting full-on running shoes. Still, even "cool" running shoes have made their way on stylish European feet.
Comfortable "athletic lifestyle" footwear appropriate for kilometers of city walking are made by Nike, New Balance, Puma, Adidas, etc. that also look great. If you wish something a bit more stylish, another great choice are a pair of understated leather sneakers.
Basically, you should not feel compelled to wear elegant "dress" shoes. See some of my preferred travel shoes by consulting my guide on the finest travel shoes for guys.
Flip Sandals
Save the flip-flops for the shore.
Short
Although Europeans may not wear shorts as often as Americans, you will find plenty of them sporting shorts all throughout the continent—particularly in the warmer areas.
Avoid athletic shorts is the secret. Another signature of the conventional American tourist are khaki cargo shorts.

Sweatpants and Athletic Pants
I advise against wearing sweatpants in public as you seldom find Europeans doing so.
Since athletic pants are also unusual, my general guideline is to avoid anything resembling what you would wear to run or play soccer.
Many firms, however, create trousers with performance fibers yet cut and style like regular pants. If you still want the comfort of "athletic" trousers without seeming as like you're preparing to work out, they might be a decent choice.
American Baseball Cap And Other Sporting Fan Gear
Although baseball-style hats are not unusual in Europe, donning a cap from your hometown sports club will usually make you seem like an American visitor. I advise dressing in a basic hat or one devoid of sports team branding.
Conversely, Yankees caps tend to be among the most sought-after fashion accessories among Europeans, so always has a choice.
If you want to fit in, other fan apparel like shirts and coats will also identify you as a tourist and avoid items like that.
