And while I don't have a PLETHORA of pics to choose from (aka Ren Faire and Prom), I did participate in some traditional Korean folk dancing for a community multicultural festival back in 1985 (I was 14).
When I mean "participate", I mean my mother made me. We did have some pretty white dresses for other dances but for this drum routine, we got to wear these fantastic outfits.
I'm the "little boy" on the far left.
