Men, do you still have clothing from when you were a pre-teen or a teenager, and does it fit?

I 45m and was recently going through some boxes at my parents' house when I found a Houston Oilers windbreaker that I got when I was 12 years old. Amazingly, it still fits me. I also still have and occasionally wear a custom Houston Astros jersey with my last name and baseball number on it, which I got when I turned 16.
