Double layer dress. Full under shell. Size and material tags missing. I'm almost positive that the floral fabric is rayon. The black shell underneath seems to be a poly/spandex type material. Please see the measurements in photos. Dress should be a size 16/18 depending on your specific measurements. I'm happy to take additional measurements and answer any questions. Although I try to take the most accurate photos possible, please understand that color may vary depending on lighting and the device you use to view listings. Make me an offer! Bundle for discounts! Feel free to ask questions! Thanks for looking!
