Dark fruits dress by Cider Brand New size 4X fits more like a 2X

V-neck dress with a linen-like feel to the fabric (it’s polyester) corset style middle, sleeveless, midi length. Marked a 4X, but I’m a 3x-4x and couldn’t get it on. Maybe more like a 2x. Material has no stretch. Gorgeous print with cherries, blueberries and strawberries on a black background. New with tags.
