Striped blazer from Anthropologie

Black and cream stripes on this casual blazer with an unfinished hem- cotton, polyester, and spandex. Not lined (except for upper back) so it feels lightweight, good for layering. Shoulder width just under 17". There is no size on the tag- it fits like a medium on 44-35-45 measurement lady. Minor pulling under armpits, see photos. Make me an offer!
