I actually know this one.
Or should know this one.
She's fairly famous, both the cosplayer and the character, but I've been beating my head about her for a month now and I still don't remember which fighting game she's from.
I must be getting old.
Someone please tell me what character she's cosplaying?
...wasn't it a "Mai" something?
EDIT: Thanks to Sweet and Horror for commenting to say this is Lei Fang from the Dead or Alive Series!
