oh shit I remember going to one of those when I was in 2nd grade on a field trip, it was kind of weird walking around in a school uniform while everyone else was all dressed up for it.. I remeber seeing these tiny drum cymbals you can put around your finger or w.e. and I wanted it SO BAD I even asked people around me for money and begged our chaperone for it, but I never got it ):
Ah, those tiny drum cymbals.......I hated those.
Honestly I never really dressed up since I couldn't really afford to get that metal armor or custom clothing whenever I went. Just had more important shit to buy first. Really, if you can impress some people (some how ._.) they're so into it that they'll give you shit. I still think those duels are really intense.
I guess if a Comic Con or any other one of those conventions come up around Las Vegas I'll try to dress up as doctor purnell with a gas mask, although nobody would know who that is. If anyone knows of any near here please tell me, I really need an excuse to buy one.
