Generally, suits have a washing label, a welt, a trademark collar, a trademark waist, and a waistband.

The washing mark is usually inside the pocket of a suit jacket. The function is to introduce the fabric composition, size, item number, model, specification, maintenance and washing precautions, etc. The trademark is usually placed directly under the pocket opening on the inside of the chest. The merchant's brand collar and trademark are in the middle of the inside of the collar. The merchant's brand is on the waistband of the pants, on the inside of the left side of the pants.

The merchant's brand pants have a wash mark on the inside of the left side of the pants. The function is the same as the washing label on tops. The internal label allows you to clearly understand the size of the clothes, fabric cleaning requirements, and brand name.
