I've only just managed to grow mine to the point where I could call it long..ish. LOL.

I like to wear mine in a side pony (yanno, so it sits just behind one ear?) and am also growing my fringe out so just pin it or put in a side comb (which works waaaay better on my hair) with a bit of a 'bump' at the front iykwim?

I also love two ponies or braids that looks cute and you're definitely young enough to get away with it I'm kinda border line at my age

What about cutting a fringe in? That totally changes your look without having to cut your hair shorter. I had one for about 3 years before deciding to grow it out cause I needed a change but I loooooved it. Was so quick and easy to just pull the back up and it always looks 'done' iykwim? If you don't like it you can always pin it back or sweep it to the side while it grows out.
