That is EXACTLY what our gym uniforms looked like. Ours were a particularly disgusting shade of pea green and guaranteed to fit no one.
They came in three sizes: too small, too large and a combination of too small and too large. Depending on your body type, they were either too short in the crotch or hung down to your knees.
We had to write our names on them in permanent laundry marker so there was no chance of passing them down to the next sister, so everybody had to buy a new one. They were supposed to be folded neatly and then taken home every week for laundering, but of course we forgot. So we had to show up in hideously wrinkled gym suits and get marked down for it.
I despised gym class, too. I was dreadful at anything that required coordination, throwing/catching balls or climbing ropes. Every Friday, we also had folk/square dancing during the second half of gym class, which meant the boys came over in their sweaty gym clothes and we had to dance with them in OUR sweaty gym clothes. Once a month, we had ballroom dancing and we didn't have to change into our gym wear - HOORAY!
The worst part of gym class was the legendary and dreaded "sex talk" we got the first half of our sophomore years. We had to watch a very graphic movie about venereal diseases and get "the talk" from our respective gym teachers. I just remember our gym teacher (who lived with the other female gym teacher and was exceeding "manly") telling us that boys had nothing else on their minds but sex because their sex organs were on the "outside" and that it was up to us girls to "keep things under control" because they couldn't control themselves. She once told us to avoid dates in restaurants with white table clothes because the tablecloths "made the boys think about 'bed'". Pretty warped, huh?
Some particular sadistic individual also thought it would be fun occasionally for both the boys' and girls' gym classes to get together and play dodge ball. Man, it hurt like the dickens getting hit by a basketball thrown by a football player.
I thanked my lucky stars that only two years of gym class was mandatory in high school.
I really enjoyed the one phys ed course I had to take in college. It was called "Body Dynamics", nobody cared what you wore, the Teaching Assistant who was in charge spent most of her time in the corner of the gym talking to her boyfriend and we all sat around painting each other's fingernails. Now, THAT I could get into.
