This was something I was trying, but failed at what I wanted it too look like, but was not UNHAPPY with how it came out. I think I may fail painfully with my explanation though and I apologize if it is not clear.
Section out a part from the top and to keep it separate from the rest of the ponytail just use another elastic to keep it out of the way.
Now you are going to be a little awkward, but do a waterfall braid leaving the hair flowing towards the face. I had to use a clip to keep the falling part of the braids out of my way.
Once you are to one side you will continue braiding really loosely and braid in those fallen braids into a little funky top on top of that ponytail.
At this point I was just free-styling with this hair do, but I was happy with the outcome. Even though it was very different than I had pictured it. I swept the bottom of the ponytail up and under securing with bobby pins.
