Heavy Silk Fabric Names: Crepe, Duchess Satin & More

What is a heavy silk fabric called?

Heavy silk fabric is often called silk crepe (especially heavy crepe), silk satin (like duchess satin), silk faille, or silk shantung—names that point to specific weaves and finishes rather than “silk” alone. In apparel, “heavy silk” usually means the fabric has more body and drape control, so it holds structure in pieces like blazers, skirts, and dresses instead of collapsing like a lightweight charmeuse.

If you’re shopping, look for descriptors such as “heavy,” “double,” “duchess,” “faille,” or “structured” alongside the silk name. Weight may also be listed in momme (mm); higher momme typically signals a denser, more substantial silk.

Common types of heavy silk fabrics

Heavy silk crepe (crepe de chine, crepe back satin, double crepe): Slightly pebbled surface with a fluid-but-substantial hand. Great for garments that need movement without looking clingy.

Duchess silk satin: A thicker satin with a smooth face and firm body. Popular for formalwear and structured silhouettes.

Silk faille: Noticeable ribs and a crisp feel, often used when shape and definition matter.

Silk shantung: Textured with characteristic slubs; can range in weight, but heavier versions offer a tailored, architectural look.

How to choose the right “heavy silk” for a garment

For clean tailoring and a cinched waist shape, a structured silk (like faille, duchess satin, or a heavier crepe) tends to perform best.
