Maxi Dresses and skirts?!

Yeah, there cute if your a runway model, but would it actually look good for a 13 year old girl to be walking around the board walk in one of these?
Maxi dresses have made a comeback this season. They were popular in the late 70's along with the boho look. They went out of style but they are back now! Evey fashion magazine I read is talking about these. Bye-bye mini skirts, hello maxi skirts! I don't know about you, but I wouldn't be caught dead in a maxi dress. What do you think?
