Thank you for viewing. These are maternity skinny pants. The waist has an elastic band. I purchased them in the US, so the size is PXS, but I usually wear Japanese size S to M pants. I've included photos with measurements so you can check the size. The knees are a bit faded. Personally, it doesn't bother me much, but please check the photos and consider before purchasing. Shipping: Yu-Yu Mercari Delivery Thank you.
