I seem to remember a store called "County Seat" that sold Levi's jeans and cords. Speaking of cords, I remember having a pair of baby blue Levi's cords, which I wore with a baby blue turtleneck and a navy blue sweater.
Once I hit junior high, it was all about the designer jeans, like Jordache and Sasoon and Gloria Vanderbuilt. We also wore fair isle sweaters with turtlenecks, plaid shirts with the collar buttoned up and a ribbon bow (who created that style and what were they thinking??

) And I do remember the iron on transfer shirts. I had one that said "One Wild and Crazy Gal"! LOL We used to get the baseball sleeve shirts too, and get our names ironed on the back, or down one sleeve. ETA: Kilts, with knee socks and penny loafers. I had the whole navy blue/green preppy thing going on, with a fair isle sweater and a turtleneck!
And you weren't anybody if you didn't have Nike sneakers. I can remember DYING for a pair of white leather ones with a red swoosh. I was in 6th grade, and my parents wouldn't buy them for me until my Thom McCann's wore out. I did everything in my power to mutilate those suckers!

By the time I got my Nikes, EVERYBODY had them.
