Vintage 80's crocheted handmade cardigan

Amazing vintage sweater. A bit decade defying....could have been made anywhere between the 1960's or 1980's, though I'm leaning towards the latter. Handmade, crocheted knit in bright turquoise and navy. Geometric square design is accented by round holes inside each square. Juliette sleeves, slight mandarin collar. Gold buttons down front. Cropped. No listed brand or maker. Fits XS/S but see measurements to confirm. Bust - 42 Sleeve - 24 Length - 20.5
