Personally, it's very important, not only in the workplace, but also in personal life.
Because what you wear can reflect a person's external image, and the external image will affect your first impression on others, people will inevitably give themselves a simple judgment based on the first impression. Although you will find your own bright spot in the future contact, it is only when you have time to contact each other.
in the workplace, the relationship between colleagues is actually reserved. Then dressing appropriately is a way to show yourself, and it is also a way to respect the people you want to contact and the company you work for. In society, unless you have been recognized by everyone in some fields, there is no image that others can accept. Who has the leisure time to understand their internal and external strength?
Of course, the clothes mentioned here don't have to pursue big names or expensive prices, but mainly dress appropriately and conform to the environment. For example, a few years ago, the media reported that a white-collar worker ate instant noodles for several months just to buy a brand-name bag. After buying the bag, he went to the bus and continued to chew instant noodles. He had to be careful when using the bag, and he was reluctant to change it for a new bag for many years. Everyone has his own pursuit for such a thing, so I won't comment here. But my personal understanding of propriety is affordable for my own consumption. It is also very happy to have spare money to treat myself without making some strange dresses, which is in line with the scene.
In the workplace, if the company requires to wear professional clothes, they should wear them according to the company's requirements, and they can make some details to suit the public's aesthetics. If the company doesn't require dress, it should also be neat and clean, in line with its own professional requirements. Strange clothes can be your hobby, but don't bring your hobby to work. It is defined as strange clothes because the public has not accepted such clothes and fashion.
Finally, in the workplace, one should not only consider one's own preferences, but also care about the image of the company. If it doesn't help your work, it won't hinder you, and you can do your work better.
Now look beautiful and decent. There are many tutorials on the Internet. Dressing appropriately is not dirt, but your own image management, which can reflect your own self-management ability.
