These are NEXT brand checkered pants. They are slim-fitting, like leggings. The tag says 104cm, but I think they've shrunk after washing, so I've listed them as 100cm. I wore these often, so there's some noticeable pilling. They are thin but warm, and I think they can be worn in early spring. Would these be suitable for a change of clothes at nursery school? There are no stains, but there is a used feel, such as fuzzing, so please understand this before purchasing.
