I don't know where you grew up but NY, PA and OH: Yes, girls had boufants and ratted hairdos, boys had short hair and sport coats in 1965. In fact in 1968, there was only one guy with long hair (over ears) in my whole school. Unfortunately, we didn't have any surfboarding either in suburban NY. Lame movie... good soundtrack.
