Vintage 1960s tie sleeve slash neck top diagonal stripe orange and white medium

Super cute summery top in a comfortable knit material. True vintage, probably from the late 1960s— I’m not sure. See pics for the neckline and hemline where the threads are loose at the slash neck opening and the hem rolls under at the bottom where stitches busted. Pit to pit approx 18” (variable due to dolman style sleeves) Waist 16” Length 19”
