My very first costume (at least, my first since I knew what cosplay was and that anime conventions existed). I really like not having to wear a wig for this. To give you an idea of how often this has been worn, the pants have been replaced at least three times (the gloves and belts have also been replaced several times, but that's because I kept losing them- no longer an issue).
I also regularly have a companion for this costume - Spunky the Plushie, who poses as Mary's dog, Anton.
Due to burnout and having largely fallen out of the "King of Fighters"/"Fatal Fury" fandom, I don't wear this costume nearly as often as I once did- only *very* sporadic appearances if that (and usually as a "lazy" costume) these days.

The pic of me and a Terry cosplayer from 2001 was Cammyfan.com's "Cosplay Picture of the Week" for the week of November 28-December 3, 2006- does that count?
