Tan France shares the 2 items you should never wear in Europe if you want to avoid looking like a tourist

• Tan France shared his tips for dressing chic in Europe — and how to avoid looking like a tourist.
• France told Insider that wearing socks with sandals is "very much an American thing."

As people from around the world flock to Europe for their summer holiday, there's been no shortage of tourists behaving badly.

So we wouldn't blame you for wanting to blend in as you traverse through Parisian cafés or Italian beaches. Thankfully, Tan France is here to help.

The "Queer Eye" star recently spoke with Insider about his new style guide with Trainline. He also shared some of his tips for dressing chic in Europe — and how to avoid looking like a total tourist.

France said you should never pack a clothing item that's become stereotypically associated with the country you're visiting.

"The best example I can give you is a beret in Paris," he said. "They're not really wearing those, and you might embarrass yourself."

"A beret is real cute — wear it in America, wear it somewhere else, maybe just don't wear it there," he added. "Anything that you have seen in a cartoon and you're like, 'Oh my God, Parisians wear this' — that's a cartoon, that's not real life."

Another tourist giveaway is wearing socks with sandals, he said.

"I know it's become a trend, but it is very much an American thing," France said. "So if you don't want to stand out as an American tourist, the socks and sandals can stay at home."

France has more tips for dressing like a European in his Trainline style guide, including ditching your camera bag and bucket hat.

The fashion designer also shared some of his vacation packing tips with Insider, including sticking to cotton and linen fabrics to stay sweat-free in the scorching summer heat.

"Anything that feels cumbersome is going to feel horrible when you're in a place that doesn't typically have air conditioning, and most places in Europe don't," he said. "You might have a gorgeous silk dress, but silk does not do well in humidity or heat."

And when he's traveling around Europe, France always tries to stick to just a carry-on.

"Getting around is so much easier with a carry-on bag," he said. "And quite honestly, if you're going for four to five days, you can get everything you need into your hand luggage without an issue."
