Vintage Saks cashmere sweater

Vintage Saks Fifth Avenue sweater in teal. Color is a little lighter/brighter than in pics. Has a tall fold over neck. I found this at a Salvation Army about 20 years ago. It is missing the tag, but it is the same size as my other large sweaters, so I’m assuming it is a large. It is possible that it is a cashmere/wool blend, but it doesn’t feel like a blend to me. It is very soft. It is still in good condition. It was probably supposed to be dry clean only, but I always just did a hand wash and lay it out to dry.
