St. John knit tan three button classic blazer jacket

Very pretty St. John three button tan or beige blazer jacket. Deep V neckline, St. John’s signature fabric. The fabric drapes really lovely. The size tag has been cut out. I am a size 6 and it is a touch too big for me but I would wear it still as a six. I would say this is probably a size 8? but please go by measurements for proper fit for you. Bust measures 19 inches across, length 28 inches long Has stretch.
