Suit refers to western-style clothing, which is a European-style clothing relative to "Hanfu". In a narrow sense, it refers to a western-style coat or suit. Suits are usually the first choice for employees of companies and enterprises and men in business situations. The reason why suits are enduring is that they have profound cultural connotations. The mainstream suit culture is often labeled as "cultured, educated, gentlemanly and authoritative".

Suit has always been the darling of men's wear kingdom, and "suit and tie" is often used to describe gentle gentlemen and handsome men. The main features of a suit are its crisp appearance, smooth lines and comfortable wearing. If you wear a tie, it will look more elegant and simple. In addition, in the increasingly open modern society, suits, as a clothing style, have also entered the ranks of women's wear, reflecting the independence and confidence of women as well as men. Some people call a suit a woman's ever-changing coat.
