Hair, the kind with long hair (no bangs on the forehead), can be rolled up or tied in a ponytail, and the hair should be tied in a high ponytail. If long hair has bangs, it should be tied into a ponytail, which looks refreshing because it can expose ears. You can wear your hair shoulder-length with bangs, or you should show your ears. If short hair has bangs, you don't need to do more modification. Just comb your hair smoothly. Of course, you can use headdress to match your hair, which depends on your clothes!
As for makeup, if you perform in the audience, eye shadow, blush and lip gloss can be thicker. If you are performing in the square, you can use life makeup, and the makeup doesn't need to be very thick, which is naturally the most beautiful!
And shoes, you can wear high heels to set off the whole person's slender, don't wear sports shoes and board shoes, you can wear women's shoes or high heels!
Other accessories, I think can be ignored. If you have pierced your ears, you can wear earrings, not those long earrings and ring earrings. Solid color is the best color. Personally, I really don't need to wear a necklace and bracelet, unless the neck is a little short, you can use a necklace to decorate it!
