I purchased these from an online shop selling Korean children's clothing. The sizes are listed as S and M, but the waistbands are elastic, and they fit sizes 80-90 (for children aged 2-3 years old). The silhouettes of both pairs are super cute when worn. They're made of sturdy fabric and look warm. They're available in a maroon color and a wine red color, both suitable for boys. I bought both for around 2000 yen each. ■ Maroon Pants Made of sturdy cotton fabric with a gentle brushed lining. Suitable for wear from autumn to winter. ■ Wine Red Pants These are a harem style with a relaxed fit around the bottom. They're made of soft sweat fabric with a brushed lining. The color faded slightly after washing, but it's not very noticeable. Both pairs can still be worn. I'm also selling other winter clothes for children, so please take a look if you're interested. Please understand that these are used items.
