I believe it's a sample dress because there's no manufacturing tag, only an empty sample tag. so size is an estimate. silky material and lined, the zipper is probably the smoothest one I've encountered (oddly specific I know). Material is definitely more structured and keeps a slight A-line shape. IT HAS POCKETS!! Super cute makes me feel like I'm going to high tea every time I wear it. 13" pit to pit 33.5" length
