Suit trademarks are usually placed on the cuffs. According to international practice, the rule when wearing a suit is that the armband must not be visible.

As for why suit cuffs need labels:

Label is used as a packaged finished product on the cuffs of high-end suits for easy identification. People can identify the brand through the cuffs without flipping through the suits, which avoids unnecessary mistakes. The deformation of the suit caused by tampering affects the appearance and price of the suit. Therefore, in terms of design, only a few stitches are used to make it easier for buyers to dismantle.

Suit broadly refers to Western-style clothing, which is European clothing compared to "Chinese-style clothing". In a narrow sense, it refers to a Western-style jacket or Western-style suit.

Suits are usually the first choice for corporate employees and men in business situations. A very important reason for the enduring popularity of suits is that they have profound cultural connotations. The mainstream suit culture is often labeled as "cultured, educated, gentlemanly, and authoritative".

Suits have always been the darling of the male clothing kingdom, and "suits and leather shoes" are often used to describe elegant gentlemen and handsome men. The main characteristics of a suit are its crisp appearance, smooth lines, and comfort. If paired with a tie, it will look more elegant and simple.

In addition, in the increasingly open modern society, suits as a style of clothing have also entered the ranks of women's clothing, reflecting the same independence and self-confidence of women as men. Some people call suits a woman's ever-changing coat.
