The Ralph Lauren Denim & Supply blouse of dreams!! It's a poncho style, slightly cropped, off white and 100% cotton.

Size XS (I'd say it fits up to a size 12 - modelled on a tall size 12 for reference)
33'' across chest
20.5'' from shoulder to hem

Used. In great condition apart from some yellowing of the label (as shown on picture 4).

Any questions, just ask
