This is a really good question, and it’s one I’ve always kind of wondered about myself. The earliest thing I can remember was in elementary school, when I had to play a leprechaun. My mom decided putting me in a green shirt, green shorts, and green tights was the way to go; I remember after the show, I had somehow forgotten to bring socks with my change of clothes, so I wound up wearing the tights the rest of the day under my pants.
I hid those tights in the bottom of one of my drawers, and secretly wore them whenever I could until I finally outgrew them. I was always jealous of my sister and my cousin at holidays, because they always got to wear pretty things and I had to wear pants and a tie.
I still hate ties. 🙂
