Here's a style wave for ya if you want something a little edgy with a twist of 80's with currently trendy.
Let's start with the hairdo which is pulled back into a single braid that sits at the top of the crown. It sits high on the head and dangles down the back like a ponytail. All strands are pulled straight back for a slicked back appearance. The braid itself is narrow rather than bushy. You can tell this model has relatively fine hair and the end of the braid is quite thin.
