Vintage NWT Velveteen maxi hunter green sleeveless size 12 or 14 wrinkle free

vintage new with tags velveteen sleeveless maxi dress deep Hunter Green Marked as size 14, however I find with vintage items they tend to run about a size smaller so more like a size 12, but does have good stretch to the fabric the fabric does not wrinkle. It’s been folded up in a bag for quite a while and no wrinkles. Measures 55 inches from top of shoulder to bottom hem Please see measurements in photos Very soft, velveteen great for the holidays!
