Campaigne geometric lined peasant top

Here’s one for Fall! This blouse is so comfortable and goes with anything. It has a scoop neck with mock cinching tie. Full bell sleeves, and a lined bodice. So lightweight! It has no fabric tag, but feel like a silk blend. It’s in good condition, but does have some slight staining on one sleeve (see picture). Size L and Measures 27” from shoulder to hem and 22” from armpit to armpit.
