This is a set of three maternity pants: two from Uniqlo and one (jeans-style) from Nishimatsuya. I used these frequently during my pregnancy. There are no noticeable stains, but the elastic on the waistband of the navy blue Uniqlo pants is a little stretched out and wavy. The two Uniqlo pants have adjustable elastic waistbands. Both are size M. The pants from Nishimatsuya are made of warm fabric on the inside, so they're for winter. The size is L. I bought these about a year ago. No stains, tears, or odors.
