Men's knitwear from the 90s. I purchased this new at a boutique in Tokyo back then. (One owner) The brand is SISLEY, made in Italy. This brand was founded in Italy in 1974 and is operated by the Benetton Group. The color is green. The material is listed as 78% acetate and 22% wool. Actual measurements are: length 60cm (from the back of the collar down) and width 60cm (under the armpits). (Measured flat) The fit is just right for a man who is 170cm tall and weighs 64kg. There is no size label, but I've classified it as a size M.
