Happy zentai singers

Have you worn zentai full bodysuits to join in a party? Probably yes. And have you ever stood on a stage and sung a song in zentai? Maybe not. Look at them, they are so excited and happy. This is really crazy.
Because we all have the different voice, some people will have a perfect voice and they are welcomed by the audience. For the people who don't have a wonderful voice, they are shy to sing a song on the stage. Is there any good ways can save this problem.
Yes, you can wear the full bodysuit when you are standing on the stage. The other people will not know your name and appearance so that you can sing a song without any nervous feeling. Do you want to have a try?
