I like this costume because it's most recognizable, I’ve never been out in it and not recognized (except when I had to wear it on the subway to BAAF 2001 and non-otaku asked if I was Wonder Woman...) It’s actually not made to my measurements, so the first few times I wore it, it was slightly loose on me, but as I've gotten older I've "grown" into it a bit more. I've worn it once to every con I've been to, so unless I go to new cons, this probably won't be seen much more.
Update! As Avian Firefly has since made me a new fuku to match the rest of Outer Power, Inner Beauty, this first version of Sailor Mars has been retired.
