IKsolver

Got a lucky reverse image search, seems like she goes by Vivien Pável (or possibly Vivien Párkáni-Pável).

I'm curious as well. Hopefully some leads turn up soon.

I'm also wondering who she is.... She's done some stuff for a brand called petite cherry before, but that unfortunately hasn't brought up any leads. It's possible she worked with an agency that Karilyn Folker worked with before, since the two have shown up together before....
