What's the weather like in Europe in early August? /kloc-how many clothes and pants should I bring to 9 countries in 0/2 days?

The country you are going to is really hot only in Italy. In France, I don't know which city you are going to, but Lyon is very hot, and Paris is similar to other countries you are going to. It's hot during the day and cool in the morning and evening. In Germany, Munich is similar to Austria and Switzerland, and in Berlin, the weather is basically the same as Belgium and the Netherlands. The maximum is close to 30 during the day, 20 at night and in the morning, and now sometimes it is only 17 degrees.

Europe is very clean, and clothes are hard to get dirty. I suggest you take:

T-shirts, 4 pieces

Casual pants: 3 pairs

Shirts, two pieces (some restaurants in France require formal clothes to enter)

1 coat (sometimes cold in the morning and evening)

I suggest you buy two vests or undershirts made of special materials, such as Modal's, which are very effective in ventilation and perspiration. If you wear them beside you, they will be comfortable to wear in summer. We sometimes wonder that foreigners always wear undershirts under T-shirts and shirts. It looks hot, but it's actually much cooler than wearing it directly, because clothes won't stick to it.

You must wear sunglasses.

It is cheaper to buy clothes in Europe than in China. If you can't, you can go directly to Benetton. Half price in summer is available in big cities.
