Generally, the exposure of trademarks of big brands is a symbol of identity, but according to international practice, it is forbidden to see armbands when wearing a suit. As a packaged finished product, the label on the cuff of a high-end suit is easy to identify, and people can identify the brand through the cuff without rummaging the suit, so as to avoid the deformation of the suit caused by rummaging and affect the beauty and price of the suit. Therefore, in the design, just use a needle and thread to sew a few stitches, which is convenient for the buyer to dismantle.
