Vintage 70s St John 2pc Pleated Skirt Suit Set Santana Knit Black 4

Vintage 70s St John for Saks Fifth Avenue Santana knit 2pc skirt suit with long line button front top with band collar and midi length accordion pleat skirt. No size tags on this beauty, but it is a little snug on my size medium dress form so I think it would fit a size 4 best. Please note the measurements to ensure the proper fit for you: Jacket measures 25 inches shoulder to hem and 16 inches armpit to armpit with crochet edging and glossy black domed buttons that come to a subtle point. The skirts measures about 13.5 inches straight across the waist and is 27 inches long. There are no tags in the skirt, but the word “front” is stitched into front of the waistband so you put it on correctly. No holes or snags noted. This is a unique set! I have not seen this one before.
