80s vintage black rainbow funky crazy abstract print embroidered knit sweater

this crazy vintage pullover sweater by i.b. diffusion in the late 80s or early 90s features a bold and textured abstract embroidery knit design on the front, and solid black colored sleeves and backside. I like that it is casual and comfortable, but also super unique. the sweater has a crew neckline, long sleeves, and is ribbed at the neckline, cuffs, and bottom hem. the fabric is untagged but it feels like a cotton/ramie blend (all natural fibres) and the sweater goes on with a pullover closure, and is unlined. such a fun and maximalist piece to wear in dreary cold weather! tagged as size large, and I would say this fits womens size medium or large. in good vintage condition with minor staining, light fraying and light pilling. measurements (lying flat): shoulder seam to shoulder seam: 23” bust (armpit to armpit): 22” across (44” when doubled) sleeve length (shoulder seam to sleeve cuff): 19” armpit to bottom hem: 16” centre back length: 26” bottom hem opening: 21”
