Jones New York sz 16 100% silk Black (longer) Blazer Dressy Formal

An oldie but a goodie and back when these blazers were made of top quality fabrics. In this case, 100% silk (lining acetate). Has a lovely sheen to it. Dress up or wear casual w striped track pants and a white tee. Condition notes: 2 small (assumed) loss of colour spots on back near bottom side so not quite as noticeable as mid-back or front. See last 2 pics for close-up and where it is on jacket. I have only used Dryel on this, so perhaps a good dryclean would solve problem but I do believe colour loss as opposed to spots…
