Where I grew up it was Adidas with the 3 stripes. Pity the poor kid that had some off brand with 2 or 4 stripes. They were a marked man.
If your jeans were not Levis that was also a very bad thing.
My parents would not let me grow my hair long so I "could be different like everybody else". I had to run away from home over the hair issue. I lost that battle.
Now I'd be happy with long hair, short hair or any hair.
Ahh memories. :-) :-)
