Winter Peony dress

Punchy floral printed pencil dress with asymmetrical cascading ruffled shoulder and exposed gold zipper back. Unfortunately, the tag fell out and I don't remember what size it is. After doing comparisons to others who were selling the same dress, I'm guessing it's a 4. The measurements are: 36" bust, 29.5" waist, 32.5" long from shoulder to bottom hem. Otherwise, In perfect condition!; only worn once.
