These are UNIQLO leggings. Size is 100. The bear pattern in photos ④ and ⑤ has been worn very little. The denim-style ones in photos ② and ③, and the striped ones in photos ⑥ and ⑦ have brown stains from mud on the knees and seat, and some stains that won't come out. The Mickey Mouse pattern in photos ⑧ and ⑨ is not new, but still in good condition. Would these be suitable for a change of clothes at kindergarten or daycare? Please refrain from purchasing if you are sensitive to imperfections or are very particular.
