POV: dress recycling

Me (in the white blazer) and my friends at a recent semiformal

As a little girl, I loved playing dress-up. Years later, that's still the status quo. But after the high school proms and college formals, I've noticed one alarming theme: I never wear the same dress twice to a big event. (God, I'm a snob!) Do you recycle your dresses? Or do you associate one dress with a particular event like I do, and call it a day? (And the little black dress does not count!)
