Greetings everyone
This post got removed from r/cosplay, so I'm reposting it here. My gf visited a party and took a picture of this lovely character. Unfortunately, I'm bad at most fandoms, so I don't have any idea who is this supposed to be. Please help discovering who is this supposed to be. Thanks!
