The size is 80cm. It's a set of a cardigan and bloomers. You can wear them as a set. The top has been worn only a few times. The bottoms were worn once. I'm selling them because my child has outgrown them. These are used items, so please consider them as such. Also, they have been stored at home, so please only consider purchasing if you don't mind minor details like wrinkles. If you have any requests, such as wanting more detailed pictures, or any questions, please ask in the comments section.
