What should I wear to France and Italy in mid-May?

Italy is a rainy country in winter, with more rain from June 65438 to April the following year. Please don't forget to bring your umbrella. It is very hot in May, just bring short sleeves and middle sleeves, but be sure to bring a coat, because the temperature difference between morning and evening is large, so you can wear it first in the morning and put it in the car at ordinary times!
