Thank you for viewing. These are gray pants from Uniqlo, kids' size. The size is listed as XS. It's difficult to tell without centimeter measurements, but according to the website, it's for 95-110cm. I've included the size chart from the website in photo ⑥. They're gray, so it's not very noticeable, but there's a slight brownish tint that you can kind of see, or maybe not... (it changes with the light?). They've only been worn a few times. The material is easy to move in. Please understand that these are used items. I am a non-smoker and I do not have any pets. I will ship anonymously. Thank you.
