**What it feels like:** by the picture, it has great volume for the skirt. and it's Dior, so it won't be polyester. It also looks smooth and sleek. This is a classic fit-and-flare dress with a fitted bodice and full A-line skirt that creates beautiful volume. The smooth, matte surface and the way the skirt holds its shape suggest a structured fabric with body and memory. <!--concierge:{"bestGuess":"Given the Dior provenance and the skirt's ability to hold such crisp, defined volume while maintaining a smooth matte finish, this is most likely silk faille or silk mikado - luxury occasion fabrics specifically designed for structured silhouettes.
