HELP and THANKSProm hair style?
With the tiara and all, wear it up.Prom hair style?
hmmmp well what kind of dress is it? is it a tube top= hair down and flowing maybe loose curls , is it a halter= hair always up, does it have thin straps or thick ones= hair can either be worn down or half up and down or all up very versitle dress. i personally think that the best prom hair dos are half up and half down and your tiara would go perfect with that kind of do HAVE FUN!

You should wear your hair down and curl it. No tiara.
