Zookie - a sari is worn over a choli which is the tight garment that bares the midriff. The sari itself is actually just a long bolt of material.
I think her upper garment is a salwar, a blouse not too different than a choli but does not bare the midrfiff.
She's wrapped in a dupatta (a long scarf) which can also be pressed into service as a head covering. When not draped over the head in the traditional style, it is usually worn with the middle portion of the dupatta resting on the chest like a garland with both ends thrown over each respective shoulder.
Despite recent changes, the dupatta remains an integral part of Bangladeshi, Indian and Pakistani clothing.
So it is my guess that she's from one of those countries.
