you should wear casual clothes ecpecially jeans.it's better to wear black pants and a nice, neat topwhen I audition or compete I always wear formal clothes, the judges like it when people do that
If I was to decide what to wear, I would go with a nice black skirt or pair of black pants (good pants, not horrible ones), and a shirt, I don't know what colour, but nothing too bright, like hot pink or anyhing flouro, I would probably wear a white shirt, a light, pastel coloured shirt, or a dark shirt, such as purple or dark blue.
