Purchased last year at a Nishimatsuya store. These warm pants are made of fluffy fleece material inside. They're simple and easy to match with anything, and the frills at the ankles are cute, making them a stylish choice even when prioritizing warmth. There are no noticeable stains, but please understand that these are used items before purchasing. ************************************************ I have many other children's clothes for sale! If you would like to purchase multiple items, please let me know in the comments before you buy. I will consider a discount, but it will be a small one.
