Analysis (whoo, scientific): At first glance this just looks like a regular braid wrapped around the head like a headband, with a circlet underneath it. However, if you look closely at picture 2, you can see that the braid is actually a 5-strand braid.

Directions: Take a large handful of hair from just behind your ear, and put the rest of the hair out of your way. Braid the handful into a 5-strand braid (see Dreamweaver Braiding for directions on how to do a 5-strand braid). Wrap the braid around your head, pinning to hold. Use a regular necklace if you like as a circlet, tucking it under the braid. That's it!
