I purchased this without trying it on, but it didn't fit, so I'm selling it unused. It has elastic in the back. There is a faint pink stain on the front of the skirt from when I purchased it. It might come out if washed. Please only purchase if you understand this. If you have any questions, please comment. Size M Length 122cm Bust (laid flat) 32cm Waist (laid flat) 37cm Please note that these are amateur measurements and may have errors. I have many other dresses and items for sale, so please take a look if you'd like.
