These are cargo pants purchased at Shimamura. They are made of a crinkly material. I bought them at the end of the year, but they were too big, so I kept them stored. I had my daughter try them on again the other day, and while the length was good, the waist seemed to be too tight... They are new and unused, but I washed them before storing them. For reference, my daughter is 136.34 (likely referring to height and weight or a size). I think they would be a good fit for a child with a slimmer build. I plan to pack them in a Ziploc bag and then an envelope. Thank you.
