Trending - plaid 'cotton' ladies shirt with white shell buttons. Size 'S'

plaid in purple, khaki and black. inside is khaki and black. 9 button front with white shell buttons. sleeves can be rolled to shorten with tabs and buttons. soft, 'cotton' but fabric tag is removed so just my guess. tagged M but pit to pit, as per picture is 17" so I am calling it small. lots of life left in this used shirt. fast shipper. smoke and pet free home.
