Lilla Rose website has a simple style called "Tails Up" that is basically a french twist with the tail sticking up, and one of these clips to hold it down. This is a fancier version of that.
Begin with a side part at the top of the head. French braid the hair on the larger side to the ear, and then braid it out to the end. Add a clear elastic. Gather the rest of the hair at the back, and braid it.
