Length is about 70cm (from the shortest part of the neckline to the hem of the skirt). The size is only listed as M, and I think it's around 130-140cm. If you're unsure, please feel free to ask about the detailed size in the comments section. I'm selling this because I don't wear it anymore. It's 100% cotton and has a soft feel. There are buttons on the shoulders and chest, which are removable. It has a slightly faded look, so I'm selling it at a low price. *The left shoulder button is coming off, so please repair it.
