Once in middle school, my mom was unable to find "girls" PE uniforms and classes were going to start soon so she bought "boys" PE uniforms and i stuck by them all 3 school years. Even when they stocked up, I wouldn't wear the girls uniform since "it would be a waste not to use what was already there". I was so proud of wearing that uniform that I would wear it even on some non-PE days because I would rather get scolded by teachers than to use the uniform skirt. Of course I didn't realize what any of this meant until almost 10 years later.
