I am sure she is Greek. Those aren't pantaloons, that is just a
crack. Above it you can see the
roll where the
fabric of the
peplos (?) is tucked in above the waist. Then the same
fabric with same pleats continues down. Like went to the ankles. Typical Greek.
Sadly she has no attributes so could be one of many.
But i would say likely to be a personification or goddess.
