The Japanese are very strict about professional clothes. Men wear soles mainly to avoid shirts sticking to their bodies after sweating, resulting in indecent visual effects, because they think that people will sweat all year round, and not only when sweating profusely. So do women. Although women's sweating is generally not as serious as men's, women must wear halter tops and other bottoming shirts outside their underwear when they go to work. In addition to a certain sweat-absorbing effect, in order to weaken the visual traces of underwear as much as possible, it is also considered indecent to expose the traces of underwear.
In Japan, some companies even have a special person to supervise whether your dress meets the standards, which shows that Japanese people are really strict about dress.
However, in China, if you wear a bottoming shirt under your shirt, you will generally think that it is an old man's performance or a cliche. This is mainly because in the 1970s and 1980s in China, your parents generally wore so-called dacron shirts, which are extremely sweat-absorbent, so you must wear a white vest as a bottoming shirt to absorb sweat, otherwise it is unthinkable to go out in summer.
Today's shirts are not the shirts of our parents' days. Generally, it is made of pure cotton or polyester cotton, which absorbs sweat a little. As long as it is not sweating, in the case of air conditioning, in fact, boys do not sweat much, and it is not a big problem to wear it. Many men also feel that it is more casual and free to wear shirts directly, and it will be more formal to wear one more base.
Therefore, whether to wear a bottoming shirt depends on your physical condition and social environment requirements. If you are not physically fit in love sweating, I think it's all right not to wear a bottoming shirt, but if you are from love sweating, you'd better wear it. If you want to have business talks with the Japanese, if you meet in Japan, you must wear it, otherwise they will think you are rude. If you are at home in China, it's up to you. Do you want to respect the Japanese's special clothing hobbies?
Finally, how to match the bottoming shirt. Personally, I suggest men wear white or gray cotton tight T-shirts, which Uniqlo sells for 365 days. T-shirts with round neck or V-neck will do. Recently, it is even popular to match high-necked bottoming shirts with shirts. Although it is fashionable, it is too picky. Not everyone looks so good. Office workers are advised to be cautious.
It is not recommended to wear a bottoming vest because it feels like an old man's style or a macho man's style, which is not suitable for daily business. In addition, the shirt must not be too thin, if the color of the bottoming shirt inside is exposed, it will be bad. Of course, I think it will be a fashionable match to show the bottoming shirt inside the shirt neckline, which will make the boys' clothes more layered, but only if your bottoming shirt is new enough and the neckline is clean and flat. If the neckline of the exposed bottoming shirt is yellow, it is really a terrible accident scene.
Finally, to sum up, in fact, wearing a bottoming shirt is a very personal matter, which has nothing to do with the soil. Whether it is low or not is the most important thing to make yourself feel comfortable.
