Vintage Rare SUSS Black & White Cropped Sweater crochet collar & front, small xs

So cute, unique and rare! Great vintage condition! * 16" armpit to armpit, from front neckline to hem = 7", back neckline to hem = 14" * Lots of stretch * Inside tag says Size 2, but not sure how that sizing works as I've seen items that say "Size 1"
