Yeah, I had something similar too.
My father took me and my brother to a car dealership in 1978 to pick up our new butterscotch-colored Chevy Nova,
and I had THAT haircut, and the salesman said to me and my brother, "You two boys can ride in the back!"
A year or so before that, I went for really short hair for the first time. My brothers all three had the Sonny haircut. Mine went from long to pixie length.
Did wear the trousers that were quite tight above the knee, and got really really wide around the ankle.
Ah, and end seventies, a bedroom in green and orange painted walls, and jute wallpaper.
