Gumi Megpoid and Aoki Lapis, two Vocaloids
Gumi because I KNOW that little hip-belt-thing will look bad until I flatten out my stomach more; hence why I'm saving her for later.
Aoki because the canon is that she's a tiny little singing fairy, and it'll just feel tacky for me to cosplay her while I'm overweight.
Also for crossplay in general, since I know I can't bind until my stomach is gone and a crossplayer who can't bind is a pretty bad thing. ;x
