What is shantung?
Shantung is a plain-weave fabric with a crisp hand, a soft sheen and small irregular thickenings in the yarn, called slubs, that create a subtle horizontal texture. It takes its name from Shandong province (historically spelled Shantung) in China, where it was woven from wild silk. The uneven thickness of wild silk filament naturally produced the slubbed look.
Today shantung is woven from cultivated silk, polyester or blends. Silk shantung is valued for bridal and occasion wear and tailoring; polyester shantung is common in curtains, cushions, costumes and budget formal wear.

How shantung is made
Silk filament is reeled from cocoons and twisted into yarn. For shantung, the weft yarn is deliberately uneven, with thicker and thinner sections. When woven in a simple over-one, under-one plain weave against a finer warp, those thick sections show as slubs scattered across the width of the fabric. Shantung is often woven with a warp and weft of different colours, which creates a shot (two-tone) effect that changes in the light. Polyester shantung uses textured or slub yarns engineered to imitate the same look.
Shantung vs dupioni
These two silks are often mixed up because both are slubbed. The difference starts at the cocoon: dupioni (also spelled douppioni) is reeled from double cocoons, where two silkworms spin together, producing a thick, irregular yarn. That yarn makes a crisper, shinier fabric with bold slubs. Shantung has finer, subtler slubs and a smoother hand.
Silk shantung vs polyester shantung
- Silk shantung breathes, feels comfortable, takes rich colour and has a natural lustre. It is more expensive, frays, water-spots and fades in strong sun.
- Polyester shantung is cheaper, resists wrinkles and water spots, and holds colour well in sunny rooms. It feels warmer to wear and has a slightly plastic sheen up close.
- For curtains in bright rooms, polyester or a lined silk is the practical choice; for a wedding outfit, silk is worth the extra care.
Strengths
- Elegant texture with a soft sheen
- Crisp enough to tailor and hold shape
- Shot colours look rich and dimensional
- Silk versions breathe well for occasion wear
Drawbacks
- Frays quickly at raw edges
- Silk water-spots and fades in sunlight
- Creases at stress points
- Usually needs dry cleaning
What is shantung used for?
- Bridal and bridesmaid wear: structured dresses, jackets and boleros.
- Occasion wear: cocktail dresses, sheaths, skirts and sarees.
- Tailoring: lightweight suits, waistcoats and blazers for warm weather.
- Accessories: ties, pocket squares, bags and hair accessories.
- Home decor: curtains, cushions, bed runners and lampshades.
How to tell silk shantung from polyester
- Slubs: silk slubs are irregular and vary in size and spacing; polyester slubs can look more regular and repeated.
- Hand and warmth: silk feels crisp yet warm and dry; polyester feels slicker and cooler.
- Burn test on a thread: silk smells like burning hair and leaves soft ash; polyester melts into a hard bead.
- Price: silk shantung costs much more; very cheap “silk shantung” is likely synthetic.
Choosing colour and shot effects
Many shantungs are woven with one colour in the warp and another in the weft. Viewed straight on you see a blend; at an angle one colour dominates. Before buying, hold the fabric up and move it in daylight and indoor light. Cut every pattern piece in the same direction, or the panels may look like slightly different colours when sewn together.
Shantung in traditional and formal wear
Beyond Western bridal and tailoring, silk shantung and similar slubbed silks are popular for sarees, kurtas, sherwanis and wedding outfits in South Asia, where their crisp texture and rich colours suit embroidery and embellishment. The fabric’s body supports heavy zari or bead work better than very soft silks.
How to sew shantung
- Plan the layout: slubs run across the width, so cut all pieces in the same direction to keep texture and colour consistent.
- Underline: silk organza or cotton batiste underlining reduces creasing and gives seams support.
- Use a fine sharp needle: 70/10 microtex is a good start; see our guide to the sewing machine needle for silk.
- Finish every seam: overlock, bind or use French seams, because shantung frays fast.
- Press dry: use a medium-low iron and a press cloth with no steam spurts, testing water on a scrap first.
- Keep edges stable: stay-stitch necklines and curves straight after cutting.
How to care for shantung
- Dry clean silk shantung garments and anything structured or lined.
- Hand wash polyester shantung only if the label allows, in cool water, and hang to dry.
- Blot spills immediately; do not rub, which can roughen the surface.
- Line silk shantung curtains and keep them out of strong direct sunlight to slow fading.
- Store garments on padded hangers in breathable garment bags.
