New with English retailer Allreds International price tag, Vintage 50s round neck button front cardigan sweater with beautifully detailed beaded placket and trim, and round pearl button closure. The only tag in the sweater is the size 40 and the price tag. I don?t know what yarn is used for the sweater, but if I had to guess I?d say lambswool because it?s not quite as soft as cashmere but not as rough as vintage wool. In fact, it may be cashmere. Lined in what feels like acetate. The beadwork is brown and mauve. It is and detailed and carries from the front to the back. They don?t make them like this anymore. Some minor yellowing to the lining in spots. Laying flat measures 23? shoulder to hem and 18.5? armpit to armpit. Based on those measurements, I think it is a modern size small, but please double check to ensure the proper fit for you.
