Not a very good cosplay. In this cosplay, Bonby looks fatter than in all the previous ones. On 2ch, it is suspected that she stuffed cotton wool into her bra to make her boobs appear larger.

Psychologically, such cosplays are usually done for emotional release, when they get tired of being beautiful and everyone likes it. Looks like Sally from the cartoon "Nightmare Before Christmas" https://youtube.com/watch?v=jagh6HIURT8 [Embed] In the 90s, as a child, I was a little scared of this cartoon.
