I have a different pair of palazzo pants that are made of a soft modal material that I love to wear at home. I do not wear them in public because the knees pop out and sag because the material is too soft. I got these because the description says 90% polyester however they are not, and the tag says 95% Modal, which I believe is a type of silky Rayon. These are not wrinkle free and the knees pop out and sag within an hour of walking.
