Maternity set. The gray sweat pajama set is also suitable for nursing. The button on the adjustable waistband of the pants is missing. The inner pants have a stamp from a shrine for the "Dog's Day" celebration. The jeans are from Uniqlo and have been hemmed. They are short. I can measure the inseam if you'd like, so please contact me. The size is M, which is a size 9 in Japan. The black pants are about 10cm longer than the Uniqlo ones. The size is M, but they are larger than the other items. I usually wear size S or M and am petite. These are used items, so please refrain from purchasing if you are concerned.
