        "photo 1: bag has a crocheted textile body rather than Coach's typical glove-tanned leather, coated canvas, or documented vintage textile constructions",

        "stitching_description": "photos 1-4: visible stitching is generally straight on the brown strap and tabs, while the crocheted body has textile construction; detailed seam quality is not sufficient for brand attribution."

        "The soft rectangular shoulder-bag silhouette is generic and does not provide a reliable Coach model match.",

        "Condition: Like New\/Mint appearance based on clean, unused-looking exterior photos, but interior construction and odor cannot be assessed from photos."
