1. **Material**: The duvet cover and pillowcases are likely made from Egyptian cotton, known for its softness, durability, and luxurious feel. Egyptian cotton has longer fibers, which make the fabric smoother and stronger, providing a high-quality experience. 2. **Thread Count**: A high thread count (usually between 300-800) indicates the number of threads per square inch of fabric. A higher thread count generally means a softer and more durable material. For a luxurious feel, aim for a thread count of at least 400. 3. **Design**: The set might feature classic or modern patterns, often in subtle colors that are easy to match with various bedroom decors. The design might include intricate embroidery or a simple, elegant finish.
