There are three main psychological reasons: one is objective phenomenon and workplace culture, and there is no special psychology. One is the psychological reason of detachment, and you can come whenever you want. One is also a psychological reason. I see through it and don't care what others think. The subject also asks what you think, and people don't care what you think.

First of all, the global workplace is mainly divided into four categories. First, to standardize the workplace, it is necessary to wear prescribed services, such as various uniforms. Second, the workplace is conservative, generally wearing suits, such as bankers and business elites. Third, creative workplaces, such as actors and models, should be different. Fourth, leisure workplaces, such as freelancers, programmers, cultural specialists, etc. Do not pay attention to jeans, T-shirts, etc. Do not change all the year round.

Therefore, people who wear sportswear may be casual in the workplace. The company has no dress code, so everyone is very casual. Nobody cares how comfortable they are.

Second, detachment mentality, detachment mentality of successful people. Ma Yun, Jobs, Zuckerberg, and so on. Those big bosses dress casually, and people don't wear suits and ties. They are tired. No one will look down on others even if you are wearing an old man's shirt and old cloth shoes. For example, Zuckerberg, who always wears denim T-shirts, leads the entire IT industry and is completely detached. People's energy is concentrated on their favorite career. Their prestige and fame depend entirely on their strength and have nothing to do with their appearance.

Third, people who see through the world of mortals don't care. Some middle-aged people in the workplace have no hope of promotion, the boss is ungrateful, the subordinates are disrespectful, and there is no need to brush their sense of existence. Even, because I am not reused, but I am rebellious, I will go my own way and I don't care about you. There are often some middle-aged middle-class people who take the bus to the dock. They don't want to curry favor with their superiors or colleagues, so they come when they are comfortable. They can't make any important occasions anyway. Put on sportswear, go to work and do exercise in the middle, which is convenient for fitness. This concept is also correct. Since there is no expectation in the workplace, it is better to practice a good figure. You live longer than others, live better than others, and you still earn money.
