The Short Answer
Satin is a smooth, opaque fabric with a high-gloss reflective surface, created by a weave structure that floats long threads across the face. Chiffon is a sheer, matte fabric with a subtle crepe texture, created by twisting the yarns before weaving. Same fibers, completely different results.

How to Tell Them Apart: The Visual Test
This is one of the easiest fabric comparisons. Hold the fabric near a light source.
- Satin: the light bounces off the surface in a bright, sliding highlight. The fabric is completely opaque — you cannot see through it. It feels perfectly smooth, almost slippery.
- Chiffon: the light passes through the fabric. You can see shadows or shapes behind it. The surface feels slightly rough or pebbly to the touch, never slippery.
If the fabric shines, it's satin. If the fabric glows (light passing through rather than reflecting off), it's chiffon.
Common in Lingerie
Satin is the glamour fabric of lingerie. Satin chemises, slips, and robes are wardrobe staples. Satin bra cups (especially in demi and balconette styles) create a smooth, polished silhouette under clothing. Satin ribbon trim appears on everything from cotton basics to lace sets.
Chiffon is the romance fabric. Sheer chiffon overlays on bra cups soften the look without adding bulk. Chiffon robes and peignoirs float around the body. Chiffon panels in babydolls create movement and a sense of lightness. It's the dominant fabric in bridal lingerie alongside tulle.
The two are often combined: a satin chemise with chiffon side panels, or a satin-bodied robe with chiffon sleeves.
