Why is this picture so hot to me, it's not even very well drawn

I mean, seriously, look at the size of her waist. And her collarbones, they're like sliding down her chest. And what's the deal with that swimsuit?

seriously guys what the fuck

swimsuit thread I guess. Or Vocaloid, or Vocaloids in swimsuits or whatever. Man I just don't even know anymore.
