Who's she ?

I think she's an Argentinian model by the name of Muriel Makowitz often working under the name of just Muriel (aka Muriel Senderos from http://boobpedia.com/boobs/Muriel_Senderos)

Evidence
I found pictures from the same set as the OP's was taken from on this page with the name Muriel. There are other pictures of her.

This is only place I found anything like the OP's picture with a name
However there are lots of pictures of her stemming from
https://www.thenude.eu/Muriel_13308.htm
e.g.,

http://www.hegre.com/models/muriel

I am sure if I looked through all references to her galleries I would find the OP's actual picture- might be in the set named Mriel - Forest Nymph, see http://www.hegre.com/models/muriel =>
