Please read my profile before purchasing (*^^*) The waist is elastic. I didn't find any noticeable stains, but please understand that there may be oversights as I am a private seller. m(__)m The item has been stored in a drawer, so if you are concerned about wrinkles or odors, please consider your purchase carefully! I have a pet (cat), so there may be some hair attached. (I will thoroughly use a lint roller, etc.) I will compress the item when shipping, so please understand. (*^^*) If you have any questions, please comment before purchasing (*・ω・)
