I've done four proper cosplays...
The first was Nash from Lunar: Silver Star Story, a rather typical non-warrior fantasy anime outfit. My mother made it; it turned out pretty well. (2000)
The second was Hiro from Lunar 2: Eternal Blue, but it's been retired. It was my first attempt at a costume by myself, and I botched it, as well as made the stupid decision to use polyester, which SUCKS to wear. >_< (2001)
Third was Ashton Anchors from Star Ocean, a flashy fantasy warrior with the fun addition of plush dragon heads. Commissioned. My favorite costume overall. ^_^ (2002)
Fourth and most recent is Shannon Kasull from Scrapped Princess, a fantasy warrior costume with rennaissance influences and a bizarre tunic pattern. Sister did the tunic (with much cursing ^^; ). I made the cape, belt, boots, pants, and ponytail, and I'm darn proud of it. (2003)
...In 2004 I kept myself busy creating, replacing, and improving cosplay accessories for existing costumes (mostly Ashton). This year I have been too broke to begin my next project just yet. :?
