It depends on how 'big' the shows is. If it is of any importance, you are sacrificing your 'look' by not having the cuffs showing at your wrists. I use to wear a sleeveless shirt, but once my coach told me that I HAD to have a long sleeve shirt on for a regional competition, I never wore the sleeveless again, even at the smaller shows. I figured, if I am going to spend the time grooming, braiding, and put out a good performance, I don't want my 'look' cheapened by not having long sleeves. Plus, it did solve the problem of "no jackets required" on the hottest days. Nothing worse than them announcing no jackets required, and then HAVING to wear the jacket, because you were wearing a dickey/sleeveless shirt on underneath!
