Vintage top KORET of California

Fantastic vintage top. Guessing 50s/60s. Like new. No size or fabric tag. I’m a 10-12, size M-L, 36C, and this fits me perfectly. I would guess Polyester or cotton/poly blend. Metal buttons. Very flattering. Lovely button accent at back collar. Approximate measurements pit to pit 21”. Pit to hem 21.5”. From a non-smoking, pet-friendly home.
