I am a 2 1 year-old boy, and I am a junior this year. Excuse me, white-collar workers, must real estate agents wear black belts? If you don't wear a black belt, you are not allowed to go to work.

First of all, formal dress belongs to business professional dress, and the dress style is more formal and business, and the black belt is appropriate.

Secondly, your belt belongs to casual cloth belt, which is brightly colored and doesn't match your pants.

Finally, it is not that you are not allowed to go to work without a black belt, but that enterprises should have requirements for employees and even corporate image.
