Female: white-based, cyan-colored cheongsam with a more retro umbrella. Side singing all walk out, more flavorful. It is best not to use the microphone in the hand, it is easier to make people feel busy (one hand umbrella, one hand microphone...). Unless you have the temperament to keep those down, it's going to be quite a drop of thunder.)
Men: Zhongshan suit? (More vintage formalized menswear, I think, don't know much about it, I'm a girl.) Then there's a woman dressed like the one mentioned above, as a backdrop, and then interacting with the singer for a bit ...... (I'm going to go off on a rant while I'm there.)
If there's a musical instrument it's a different story
