How should i do my hair for prom? By zara | September 30, 2009 - 11:58 pm |September 30, 2009 What will you look like? I have a canary yellow prom dress. Its semi-poofy, polka dotted and its a halter top. What do you think would look best. My hair is dark dark brown and fairly long. I could wear it curly or straight but i cant decide.
