First of all, you should be clean and tidy. Clothes in summer are easy to sweat, so you should change at least one suit a day. Second, you should dress appropriately and don't expose too much. Some boys are topless in summer, walking around the street in big underpants, which makes girls disgusted. Some boys are embarrassed to wear transparent clothes. Third, in terms of color matching, try to choose light-colored clothes and avoid gaudy clothes, colorful clothes and strange clothes.
