Best Prom Hairstyles for Long Hair

When worn like Katie Cassidy, a braid is utterly grown-up and perfect for prom. To get her updated take on the classic school-girl look, just let out some loose pieces around the face.

How to do it: This style works best for girls with extra-long hair. Blow out hair with a volumizing spray or mousse, says celebrity stylist Eugene Toye of the Rita Hazan salon in New York. Then, tease hair with a fine-tooth comb working in two-inch sections throughout the head. Secure hair in a low ponytail, and pull out strands around the face to loosely curl. Braid hair starting from the nape of neck, and flip the long plait over the shoulder.
