I am loving this trend so much right now! It keeps popping up everywhere, and in my opinion will never go in or out of style...too cute! Some articles that I read mentioned that your hair needs to be super long to pull it off, but I say go for it! Even if you're hair is shorter, the messy look totally works with this style, so just pin loose pieces up or let them hang down.
I've got to give it a try.
