Uniqlo maternity denim. I wore these from last fall to May of this year. There are no stains, but please check the photos for the wear and tear around the knees and seat. Also, if you look closely, there is some sun fading on the waistband from being hung outside. It will be hidden by your top, but please refrain from purchasing if you are concerned. Please understand that these are used items before purchasing. Thank you! (^_^)
