I think it's safe to say the hairstyle us long hair lovers love the most is the long, soft, straight, silky hairstyle (a la Anya, Leona, etc).
One hairstyle that I think could come in second place is the glamorous, soft, bouncy look. An example of this is Nicole Kidman's hairstyle in "Batman Forever". Amy Adams has also pulled off this hairstyle.
Anyone else love the glamorous, soft, bouncy look on a woman? Hopefully you can get an idea of what I'm talking about based on the pictures below. They're probably as close as can be to what I'm talking about.
