Hmmm I like both lengths. I think the longer hair style is more "young looking". That is not say the shorter style makes you look old. For some reason, I just equate long hair with youth. I think the shorter style looks more polished.
What length do you prefer?
Personally, I think longer hair is easier to maintain. Less frequent haircuts, and you can pull it up or back. And if it's raining, you can pull it all back into a low pony.
Hmmm I'm trying to decide by thinking outloud, and I still can't decide which I like better. I guess it all depends on what look you're going for. Young and carefree (long), polished and grownup (shorter).
