        "The silhouette is a shallow, wide woven straw tote with a single shoulder strap, not a close match for the cataloged vintage Coach leather models.",

        "Condition: Good to Very Good; the listing reports crazing on the leather strap, and photos show mild surface wear, but the bottom, interior, and lining are not shown."
