Beautiful purple and black silky plus size dress

Beautiful purple, black, and white sleeveless dress with zipper back. Only worn a few times and is in perfect condition. The size on the dress says 1X, but the measurements across the dress are Bust-24 Waist-21.5 Hip-26 making it more like a size 20 or 2X. Please note that this is one dress, but I have it listed as multiple sizes to help with searching. Fabric has no stretch so please feel free to ask any measurement questions!
