Size 130 cm. Purchased at Aeon. These are loose-fitting, thin pants. They have some stretch. The waist is elastic, and the drawstring is just for decoration. There's no opening to replace the elastic. I don't remember how many times they were worn. I apologize. These were for everyday wear. The beige ones were worn, but I don't remember how many times. I apologize. There is some pilling and some fading. The black ones don't have any name tags, but they were stored and I think they were only worn once or twice. Both pairs have marks from being clipped with clothespins on the waist. There are wrinkles from washing and storage. They have lint from being stored with other clothes. This is a personal inspection. I apologize if I missed anything. These are used items, stored at home by a non-professional, and have been worn by a child, so please refrain from purchasing if you are sensitive to these factors or expect perfection. I will compress them for shipping, so please be aware that there may be creases. I will only sell them as a set of two.
