Formal shorts for kids, size 100cm. I bought these on Mercari, but my child didn't wear them because we chose something else. I bought them thinking they'd be like knee-length shorts, but when I put them on my child, they were short shorts that showed the knees. The previous seller's child's name is written on them. The waistband has elastic in the back, and there's a button inside to make the waist smaller, accommodating a wide range of sizes. They have a faint center crease.
