Banana Republic crochet front puff sleeve knit top

Soft neutral gray cotton top, not quite lightweight sweater but heavier than a tee. Hits at hip, wide ribbed band at bottom. Slight pouf cap sleeve, crochet panel with buttons at center bust. I loved wearing with a black pencil skirt to my office and then jeans and flats on the weekend. What looks like damage or stains in photos is just the flash playing tricks.
