Tie clip – it’s the same accessory as the watches. When you wear it, you need to follow certain rules. There are three of them:
N1: A tie clip should be placed between the third and fourth button of your shirt. Not below or above.
N2: It may sound obvious, but the clip should not bind the front and back side of the tie, but the tie and the shirt.
N3: Never wear a tie clip that is noticeably wider. It looks very badly.
