I've always been a long hair kind-of-guy. But if the style of the girl fits the shorter hairstyle, I think its cute. Past trends of my girlfriends have been long hair. I think it's the ability to switch up styles that attracts me to the lengthier hair.
I typically like long hair, but some women can pull off short hair.
There's no contest here. LONG HAIR IS BETTER THAN SHORT HAIR, OF COURSE. What do I hate the most? Seeing a presenter on TV with beautiful long hair, then the next time she comes on screen, she's been "got at" and her hair has been trimmed short. Makeover programs have a lot to answer for. They always cut the hair short. This is so, so so, bad. I have never, in my whole life, seen a women that looked better with short hair. YUK. Grow it as long as you can.
