I agree, she is fantastic, but I can't find her in my database. Do you remember where you got the pic. Do you have any others with more of the background. It sometimes helps, especially with MET pics. I seems that this was taken outdoors, so that might give a clue as to the photoshoot. I'm just taking a shot here.
BTW, I don't think Milik is her name, even though it is in the photo ID.
