I bought this from Nitori about 3 years ago. I'm selling it because my child has outgrown it. I used it during this time of year and until early spring. The fabric is a bit thin, but it was just right since the pajamas were thick. There is some paint peeling on the zipper hardware and some pilling around the neckline, but I think it's still usable. There is no size label, but the flat measurements are 50 cm in length and 40 cm in width. My child was able to use it until they were about 3 years old.
