My sister is finally going to go for prom; I remember when I went for my prom. I just want her to look her best, I love her and I do not want anything to mess up this day for her. Could you give me a list of the best prom hairstyles you can find and tell me? Depending on her tube slender fitting gown with a slit and a diamond border both at the neckline and the tip of the dress, the hairstyle could be either an up do or falling down right. So what do suggest. The thing is she would look good in any; we are just confused as to which hairstyle she should wear. Up do hairstyles are so common that is why I did not want her to have that. She is known as my sister, hence I do not want her to have the up do hairstyle as I do not want people to think she has copied me. She has extremely long and luscious hair, she deserves long prom hairstyles.
