Braids were a huge hit this past summer, and definitely will be seen this fall in even more elaborate and creative patterns. I found this braid crown on Teen Vogue. I've seen other variations of this, but I like this one because of how the two braids come from either side of the head, and then are pinned in the middle. Here's a pic and link to the Teen Vogue website:
I also am loving bows, and even though they seem like a spring sort of style, I love this scarf bow idea that Anne Le posted on youtube. This will definitely look cute once the cold weather rolls in!
