I had a Ragnarok Online hirt. I didn't buy it, it was sent to me as a "gift" for my six (or was it three?) month subscribtion. There was a deviruchi holding a fork (with a hotdog) on it. I wore it to the gym that year. When clearing out some stuff from the top shelf of my closet, I found it, no idea how it got up there.

That is probably the only video game related article of clothing I own. Except for Super Mario socks.
