Vintage tailored button down shirt with floral / teacup / vase pattern size xs

One of a kind expertly tailored printed green and black button down vintage blouse, tag says Pamela Martin. The fit is incredibly flattering, it flares out ever so slightly at the hem, accentuating the waist. So classy and unique. Mother of pearl buttons. Fits like an xs, vintage size says “10” but vintage sizes are much different than modern day sizes! The consignment shop I bought it from dated the shirt to the 1940s-1950s.
