These are leggings from cofucu, made with a blend of cashmere, organic cotton, and silk. The size is 70, but they can fit up to around size 80. I purchased two of the same leggings from the online shop, and this pair is new and has never been worn because my child outgrew them. They were useful as underwear in the cold season, and also as leggings to wear on their own. Although they are unused, they have been stored at home, so I hope someone who understands this will be able to use them. ^ ^ - Brand: COFUCU - Material: Organic cotton, cashmere, silk - Color: White - Type: Leggings Thank you for looking.
