The waist and sleeves have elastic. The body of the garment is lined. There are no pockets. It's made of a thin, lightweight fabric, similar to chiffon. I've worn it about 20 times. I didn't see any noticeable stains, but please refrain from purchasing if you are sensitive to imperfections, as I am a private seller. Color: Black系 (Black-based) Pattern: Floral 100% Polyester
