I think medium length hair would be ideal for this, but it sounds like long hair would also work. The only problem I foresee with long hair is that you have so much more to deal with!
Curl, pin, and spray! Have at it ladies.
If you do this hair style, let me know if you danced in it or not. I’m going to try this out for class, but who knows if it will actually stay in. Maybe more bobby pins will be in order. Hahah, and maybe I can bum hairspray off of someone.
