These are DAILY LINE stretch pants from Birthday. This is a set of two, brown and khaki. I used these for everyday wear. The tag is marked with my name, which has been blacked out. Brown: There is a black stain on the back of the right leg. Khaki: There are marks from clothespins around the waist. I think they will disappear after washing. Would these be suitable for daycare, etc.? I am also selling other clothes in sizes 90cm-110cm. I welcome combined purchases.
