HusHusH These pants are made of a rayon blend, perfect for staying comfortable in the summer. The fabric wrinkles easily, so I would smooth out the wrinkles before hanging them to dry after washing. I didn't iron them since they were for casual wear, but ironing is probably necessary if you plan to wear them to the office or if you're concerned about wrinkles. I haven't worn them this year because my body shape has changed. There are no stains, but please only purchase if you understand that these are used items. I will fold them up small for shipping.
