⚫︎ Although it's a size M, I was using it for my child who is size 150. Of course, adults can also use it, and depending on the child's height, parents and children might be able to share it (^_^) ⚫︎ There is no lining, but the fabric and design are not see-through. ⚫︎ It's basically worn with an elastic waistband, but adjustments can be made with the drawstring (photos 4 & 5). ⚫︎ There are pockets on both sides (photo 6). ⚫︎ There are no broken threads or fraying (photo 7). ⚫︎ The length is about 47 cm to 48 cm. ⚫︎ The gray area of the elastic waistband has some fuzzing and pilling overall, but I don't think it's very noticeable (photo 9).
