What are the rules about the color of the tunic worn by a comedian?

Coat, theoretically, what color can be, but the color is too light is not good, too bright collar trick (jargon: take the eyes, you say singing how good not to look at you, net look at your clothes to go, the same, the fan can not be too flowery, the best white, on stage can not wear accessories are the same reason can be evidenced), as well as, black do not casually wear, it is rumored to be the bottom of the corner to wear. It really doesn't matter if the two are a color scheme. Here since someone asked, I will post an old article "the rules of the long shirt" Shanghai commentary actor Mr. Chen Legend Mr. oral, I am simply sorted out for future reference, not all, if there is a mistake, there may be a mistake in his mouth, it is more likely to be my handicap or understanding of the error, the words out of the problem, the order of mobilization. Please forgive me. Long shirt, the northern people called coat. These rules are traditional Chinese culture, can not comply with, can figure to save trouble, but can not not know, can not be lost, this thing no one knows, the loss of culture, the most terrible long shirt, are customized, no ready-made. Online may have, that do not know what material, length are not the same, a little difference will not fit. And the long shirt practice must be done in accordance with the old rules, now some of the online see or some even go to customize, some tailor, I see a lot of special comedian wear those, Tianjin Beijing to do it, all the patch - long shirt, because it is long, patch a lot, unlike trouser legs, trouser legs patch on the last below that point! -Must be hand-stitched on the outside can not be seen with the needle and thread. The value of the tunic is in this place, nowadays many sewing machines, not right. Buttons (button loops), the first one here at the neck, the second one must be vertical, this is a long shirt. Not authentic buttons are slanted, that's the women's cheongsam buttons, men must be straight. It's standing up, it's all sewn by hand, there's manipulation, there's machine stepping which is not right. The collar of the long shirt is vertical, now there is a slant, that is also (according to) the cheongsam (practice). If the clothes are too bright, the audience will pay attention to the clothes and not to what you are saying, which is the same as the fan, the hairstyle, and the lack of headdress. Especially men, you are not like a woman on stage, the little girl dressed up beautiful, men on stage can not be enchanting, there must be a kind of righteousness.
