nano・universe Wide Pants Color: Greige (light color) Length: Full length Pattern: Solid Material: 100% Polyester Silhouette: Wide Size: Free size (elastic waist) The fabric is light, but it's double-layered so it's not see-through and can be worn comfortably. (Can be worn year-round regardless of the season.) I've worn it a few times and stored it at home. There are no noticeable stains or fraying.
