Vintage 1970s Black St. John Knit Dress

Black Knit St. John Dress c1970s. I would guess this is a 6/8 but there is no size. There is a flaw on the upper right by the neckline as shown in the photo, and various tiny pulls on the dress. St. John can always be mended and if needed stretched. Waist is 28”. Length from shoulder is 37”. Sleeve is 23”. Please note I have noted all flaws that I see.
