This one is very similar to most that I do- front of the hair pulled back into a messy little poof/bun. I did this one a few months ago, before I cut bangs (which I do every so often, even though I decide I hate bangs just after a few days of cutting them.)
Just take the front section of hair, do a simple braid at somewhat of an angle, and attach it to a ponytail in the back. I never like to do the braid going straight back because it makes me feel like my head is pointy. Which it's not. :)
*I have done this do on Emma as well for time-crunch days, so it is another one that works for all age groups.
