Vintage Mix & Match Dark Blue Sheath Dress Long Blazer Ivory Trim XS

Mix and match with this dark blue short sleeve sheet dress and coordinating long blazer with ivory trim. the only tag is cardboard identifying this as a vintage size 7, however, please note the measurements because this is closer to a modern size extra small. The fabric looks like a nubby raw silk, but I cannot confirm if it is a natural fiber. There is an acetate lining that does show some discoloration that is not noticeable when worn. Back metal zipper branded NYNCO. The metal zipper indicates to me that this is from the 60s. Laying flat the dress measures 36 inches shoulder to him, 12 inches straight across the waist and 16 inches armpit to armpit. The jacket is 33.5 inches long and 20 inches armpit to armpit with the seam touching.
