These are linen-blend shorts from GAP, released every season. I bought them a year apart, so the material and color are almost the same, but the waist specifications are different. The ones with the waist button are 5 years old (110cm), and the ones with the waist string are 2 years old (90cm). I bought these to dress my two sons, who are two years apart, in matching outfits. The 2-year-old size has been worn about 5 times, and the 5-year-old size has only been worn once.
