I used to wear my hair down a lot more when it was shorter (an inch or two above the shoulder). I'm trying to grow it out right now and its at that really awkward stage...ugh... I hate it!! I do this every single time; I try to grow my hair, it gets to this length, I get frustrated, and then I cut it all off again.
So, right now I've been wearing it up more because it's just easier.
When it was real long I would wear it down. In the summer time I would put it up in a clip. Now that it is short I wear it down but sometime I tuck the sides behind my ears.
