Silk
A natural protein fiber produced by silkworms, prized for its exceptional softness, natural sheen, and temperature-regulating properties.
What Is Silk?
Silk is a natural protein fiber produced by the larvae of the Bombyx mori moth, commonly known as the mulberry silkworm. Each cocoon is spun from a single continuous filament that can stretch up to 900 metres long. This filament is composed of fibroin (the structural protein) surrounded by sericin (a protective gum). When the sericin is washed away during processing, the fibroin filaments reveal their characteristic lustre, smoothness, and strength. Silk has been cultivated for over 5,000 years and remains the benchmark for luxury in textiles.
What makes silk exceptional for lingerie is its thermoregulation. Silk fibers contain microscopic air pockets that insulate in cold weather and allow heat to escape in warm weather. Against the skin, silk feels cool to the touch on a hot day and warming on a cold night. This dual-temperature behaviour makes silk lingerie genuinely comfortable year-round, unlike polyester satin which traps heat and moisture. Silk also absorbs up to 30% of its weight in moisture without feeling damp, wicking sweat away from the skin.
Silk quality in lingerie is measured in momme (mm), a unit of weight. Higher momme means thicker, more durable silk. Lightweight silk (12-16mm) is used for sheer camisoles and negligees. Medium weight (19-22mm) is the standard for slips, robes, and bra linings. Heavy silk (25mm+) appears in structured pieces and outerwear-adjacent lingerie. For gifting, 19mm charmeuse or crepe de chine offers the ideal balance of visible luxury, comfortable weight, and reasonable durability.
Silk requires careful handling. Always hand wash in cold water with a pH-neutral detergent (regular detergent is too alkaline and damages the protein fibers). Never wring silk; instead, press the water out gently and roll in a clean towel. Dry flat away from direct sunlight, which yellows white silk. Never bleach silk. Iron on the lowest setting while still slightly damp, using a pressing cloth between the iron and the fabric. Stored properly in a breathable cloth bag (not plastic), silk lingerie lasts for years.
How to Wear & Style
Silk lingerie is the gold standard for gifting and special occasions. A silk robe and chemise set makes a timeless wedding night or anniversary gift. For everyday luxury, a silk camisole worn under a blazer doubles as both lingerie and a layering piece. Silk slips work beautifully as nightwear in Indian summers because the fabric breathes and regulates temperature naturally. Pair a silk bralette with high-waist palazzo pants for a relaxed evening look at home.

Why is silk lingerie more expensive than satin?
Silk is a natural fiber that takes significant resources to produce. One silk cocoon yields only about 1,000 metres of raw filament, and roughly 2,500 cocoons are needed for a single metre of fabric. Satin, by contrast, is a weave pattern that can be made from cheap polyester. The price difference reflects raw material cost, not just branding. Genuine silk also requires gentle care, which adds to the perceived luxury but is part of owning a natural fiber.
How can I tell if lingerie is real silk or synthetic satin?
Check the fabric composition label first. Real silk is labelled as 100% silk, mulberry silk, or silk with a specific momme weight. Synthetic satin is labelled polyester or nylon. By touch, real silk feels cool and adapts to your body temperature, while polyester satin feels slightly plastic and retains heat. Real silk also has a subtle, irregular lustre, whereas polyester satin has a uniform, almost metallic shine.
