What clothes should I take to travel to Europe on June 14?

The temperature in June is very comfortable, and the temperature difference between day and night in Europe is small, so there is no need to bring thick clothes. /kloc-it's almost enough to wear one set of three clothes for a 0/3-day trip, and it's almost enough to change four sets of clothes. You don't need to bring too many underwear and socks. Go back to the hotel at night to wash and dry for one night. Don't take too much, you will get something if you buy it. . .
