Menswear can fundamentally be divided into outerwear and underwear. Shirts, jackets, trousers, socks, and boxer shorts all belong to the menswear category. Menswear should be able to adapt to the external environment conditions as well as that of everyday life. A manager, for example, should go about his daily work in suit, tie, and nice business shoes. But even if you don't have to wear a suit to work, there's nothing wrong with a nice pair of denim jeans with a well cut polo shirt.
