The costumes for dancing together should be uniform (that is to say, even the rings and hairstyles on the hands are the same, at least it makes people feel like a group), otherwise others will think it is not good for several office workers to dance together.
Regarding the color of clothing, black is of course the first choice for slimming! With gold ornaments (black and white, gold, silver and gray are the best of the five colors), if the stomach is bad, usually the thighs will get better, then wear pants. Only wear dark OK belt, white or reflective shoes, preferably black or white boots, and don't wear glasses.
Ok, come on stage, please keep smiling and don't look down at the audience. By the way, you'd better go to the scene to rehearse several times. Thin coats can be slimmer, but I'm not promoting unity. Hehe ~ What color coat and shoes should be similar in color.
