I absolute LOVE this dress but it runs small and doesn’t fit. It is a 3X but fits more like a 2X so listing as 2X! Use sizing to determine fit! Stretch knit - gives you a couple inches of stretch but go by these appropriate measurements to ensure proper fit. Length 63" Armpit to armpit 22” Waist Approximately 19” Hips Approximately 27” Brand new unique boutique piece. 13-52
