I agree that she has all the details and look exactly like Lia May. My only concern is the size of the boobs. If it is Lia May it has to be an old set and Lia May had a boob job. But the Met-Art set has a copyright dated from 2006.
I didn't know her before looking at this thread, maybe you guys know if she had a boob job or not and when. Also she doesn't have the tattoo on her back right shoulder but that's not really important, most of the time they take it off with Photoshop.
In these two photographs the difference is obvious.
This is the complete set.
I'll let you decide, I don't know her enough.
