These 80cm fleece-lined pants were purchased for a birthday. They have a sturdy fabric and a slim fit. Worn twice. My child quickly outgrew them due to being a bit chubby. They should fit a slender or average-sized child. The sturdy fabric makes them quite durable. They haven't been put in the dryer. I used "Sarasa" detergent and fabric softener. Regarding shipping, I've set the date with some leeway. Please feel free to comment if you have any questions. I may change the shipping method between "Rakuraku Mercari Bin" and "Yuuyu Mercari Bin."
