Drichu Purple Cotton Blouse Made In Nepal NO SIZE XS? Pockets

Purple 100% cotton woven top with side pockets. No size, however this is most likely an XS. I wear a small/6 and it fits tight under the arms and through the shoulders on me. This is a lagenlook style so it should be a boxy loose fit. Good pre-owned condition. Approximate measurements 8.75" sleeve, 19" armpit to armpit, 27" shoulder to hem.
