I've worn this a few times and then stored it at home. It's mostly clean, but there's some pilling on the inner thighs where the fabric rubs. Washed. From Fall 2022 to November 2024, I have not had any infections such as COVID or the flu, and I do not have any pets. I am 152cm tall and weigh 46kg. When I wore it, the length covered my ankles, and it had a comfortable, relaxed fit.
