My Sadies dance is coming up soon, and I really love this Eva Mendes style, the messiness of it, but I was wondering, to put it up, should you first put it up in a ponytail and then proceed to pin up the rest? Or should you kind of haphazardly put it up like the picture and just pin it without the ponytail. I have thin hair but a lot of it, and it is about 1 or 2 inches past my shoulder. I have layers. I don't have bangs, so also how would I make the bangs that Eva has work for me? I do have shorter face framing layers in front and the shortest one is just about chin length. Detailed instructions would help a lot! Thanks.
