What should we bring when traveling to western European countries in summer?

Summer is a very good travel season in western Europe. Countries such as France and Spain are cool and pleasant, so just bring normal summer clothes. If you are going to climb mountains, you still need to bring long pants and a wind-resistant jacket. Although many people say that there are many mosquitoes in European villages, I have never been bitten by mosquitoes when traveling. If you are particularly attracted to mosquitoes, just bring a mosquito repellent toilet water. Of course, women need to bring some sunscreen and skin care products, 30-50 times is enough. In addition, if you want to go to a Michelin three-star restaurant, men need to wear formal suits, and women need long skirts or dresses before they can enter. Jeans and hot pants are not allowed. There is nothing else that requires special attention.
