Vintage 70s PYKETTES polyester pointy dagger collar top

Fantastic vintage button front shirt. Black and white Polyester crepe with black buttons. Tiny snag on the front (shown). Also small stain that is much more noticeable in the photo than in person. No size tag, but I am a medium, size 10, and this fits me. I would guess this is a ladies medium, size 10-12. Could fit a smaller large as well, as it is blousy. Hard to let this one go, but I am downsizing. From a non-smoking, pet-friendly home.
