We've all been there: The awkward outsider in a country that we clearly don't come from. Whether it's something we can't change (our ethnicity, for instance), or something we can (the way we dress) there's always a way to look a little bit less like a tourist and to blend in with the locals. Here's how.

1. Learn key words

Even if you don't speak the language fluently, it's important to pick up key words that you'll use over and over again. If you know them, you'll be that much better equipped when interacting with people on a superficial level. For instance, when purchasing clothes or food, you only really need to know a handful of words: A greeting, a number, and a parting word. And be sure you know how to say "thank you" in the local language--you'll probably use that one most of all.

2. Eat the right food

Don't fall for the perfectly manicured stores that propose "Great deals for tourists!" with menus written wholly in English. Usually, these places are filled with troves of tourists being ripped off; prevent yourself from becoming one of them. Instead, search for hidden treasures with menus in the local language, filled with people in normal, working clothes. Grab a seat and prepare to ask the waiter what his recommendation is for the night.

3. Speak quietly

Nothing gives visitors away than loud voices and incessant chatter. If you keep your voice at a level volume when speaking normally, you will likely blend in much better than if you are calling in a foreign language down the street for someone else. Watch your noise level, and you'll be sure to remain inconspicuous.

4. Dress for the right weather

While style is definitely important, it varies from person to person. Dressing correctly for the season, however, does not. Check the weather before you pack for your trip. If the weather forecast predicts nothing but monsoons, don't pack miniskirts and heels. If it shows sun for days, don't just bring pants and North Face pullovers.

5. Be polite

Strangely enough, tourists sometimes have to be reminded of their manners in a foreign country. Just because you're not where you feel most comfortable does not give anyone the right to be rude. Keep your polite ways. Trust me--those are universal.
