Robins Egg Blue Spring Shift 1970 Dress Needs Help

No tags or labels. True vintage, ca. 1970’s but has NO signs of wear. Simple V neck front, with bow trim on back. A flap covers the rear zipper, then the bow uses hook & eye to secure. NOTE: the bottom of the zipper separates when dress is zipped to the top. May need replacement & price greatly reduced to reflect this. No pockets. Feels like a medium thick polyester knit. Soft & some firm stretch. Measurements taken on side, lying flat. Bust: 19”, Waist 18”, Hips 19”. Length is 38”
