A reference guide by Opaalique — updated 2026
Fashion editors cite it. Stylists bookmark it. Shoppers send it to their friends.
This is the article they're all looking for — and most brands never write it.
A bra can be beautifully designed and still feel terrible. A set can look ordinary and feel extraordinary. The difference is almost always the fabric.
Yet most lingerie retailers describe their fabrics in the vaguest possible terms — "soft," "luxurious," "smooth." These words tell you almost nothing. This guide tells you everything: what each fabric actually is, how it behaves against skin, what it costs to produce, and which body types and occasions it suits best.
What it is: A natural protein fibre spun by silkworms (Bombyx mori). Genuine silkhas a lustrous sheen, a cool-to-warm temperature response, and a characteristic soft rustle.
How it feels: Weightless, smooth, and surprisingly temperature-regulating — cool in heat, warm in cold. Nothing else replicates the sensation.
Types used in lingerie:
Care: Hand wash cold, mild detergent. Never wring. Dry flat. Avoid direct sunlight.
Price signal: Silk is expensive. A genuine silk set from a luxury brand typically starts at ₹8,000–₹25,000+ depending on construction. If a "silk" piece costs less than ₹2,500, verify — it may be satin-finish polyester.
Ideal for: Special occasions, honeymoon, gifting, sleep luxury, editorial shoots.
Opaalique note: We use mulberry silk in select pieces — the highest-grade silk available, sourced from controlled Bombyx mori cultivation.
What it is: Not strictly a fabric — laceis an ornamental textile structure, created by looping, twisting, or knitting threads. In modern lingerie, most lace is machine-made; handmade lace is extremely rare and commands collector prices.
Types used in lingerie:
How it feels: Varies enormously by type. Chantilly is ethereal; guipure is substantial and architectural; stretch lace is comfortable for all-day wear.
Care: Always hand wash. Machine washing degrades lace structure within 5–10 cycles, even in lingerie bags.
Price signal: Lace quality is the single biggest cost driver in luxury lingerie. French lace from mills in Calais (notably Sophie Hallette and Solstiss) is the global benchmark — expect to pay significantly more for pieces that use it.
Ideal for: Statement pieces, bridal, boudoir, occasions where the garment is meant to be seen.
What it is: A weave construction (not a fibre) characterized by a long "float" of warp threads over weft, creating a smooth, reflective surface. Satin can be made from silk, polyester, nylon, or acetate.
The crucial distinction:
| Label says | Could actually mean |
|---|---|
| Silk satin | 100% silk — premium |
| Polyester satin | Synthetic — lower cost, less breathable |
| Acetate satin | Mid-range, dry-clean preferred |
| Charmeuse | Usually silk or high-grade polyester |
How it feels: Glassy-smooth on the "right" side; matte on the reverse. Drapes beautifully.
Care: Depends on fibre content — check label. Polyester satinis more forgiving; silk satin requires delicate handling.
Ideal for: Slips, chemises, robes, bralettes with structured cups.
What it is: Ultra-fine synthetic fibres (polyester or nylon) with a diameter less than one denier. Originally developed for sportswear, now standard in premium everyday lingerie.
How it feels: Silky-smooth, barely-there. The best microfibre is genuinely difficult to distinguish from silk against the skin.
Why it matters: Microfibre is the reason modern everyday lingerie can feel luxurious without the price or care requirements of silk. It's also the most hygienic option — it dries quickly and resists bacterial retention.
Care: Machine washable (cold, gentle cycle). This is microfibre's greatest practical advantage over silk.
Ideal for: Daily wear, travel lingerie, t-shirt bras, seamless pieces.
What it is: An open-weave knitted fabric. Powernet is a firmer, more structured mesh used in foundation garments; fashion mesh is lighter and sheerer.
How it feels: Breathable, lightweight, slightly structured. The openwork construction means it doesn't trap heat.
Uses:
Care: Machine wash cold, gentle. Air dry.
Ideal for: Warm climates, activewear-adjacent pieces, sheer aesthetic details.
What they are: Stretch knit fabrics made from natural or semi-synthetic fibres.
How they feel: Relaxed, soft, forgiving stretch. The "second skin" category.
Why they matter: For daily comfort and sleep lingerie, these fabrics outperform everything else. They also photograph beautifully in natural light.
Care: Machine washable. Modal is slightly more delicate — use a laundry bag to prevent pilling.
Ideal for: Sleep sets, wireless bralettes, period-friendly underwear, every day.
What it is: A woven fabric with a short, dense cut pile. In lingerie, velvet is almost always a stretch velvet — a velvet face bonded to a jersey backing for drape and give.
How it feels: Rich, warm, plush. Immediately recognizable as luxurious.
Seasonal note: Velvet traps heat — it is definitively a winter fabric. In tropical and subtropical climates (like most of India), velvet lingerie is best positioned for December–February and air-conditioned contexts.
Care: Hand wash cold. Do not wring — it permanently crushes the pile. Hang to dry (never fold damp velvet).
Ideal for: Winter gifting, holiday campaign pieces, occasion sets, deep jewel-tone aesthetics.
What it is: The world's most widely grown natural fibre. In lingerie, usually a combed or ring spun cotton for softness, often blended with elastane (2–5%) for stretch retention.
How it feels: Familiar, breathable, reassuringly non-synthetic. The best choice for sensitive skin and daily hygiene.
Grades to know:
Care: Machine washable. Avoid hot water — it causes shrinkage and fades colour. Wash darks inside out.
Ideal for: Everyday underwear, breastfeeding bras, postpartum, sensitive skin, loungewear.
| Occasion | Best Fabric(s) | Avoid |
|---|---|---|
| Everyday wear | Microfibre, cotton, modal | Heavy lace, silk (care-intensive) |
| Sleep | Modal, bamboo jersey, silk | Polyester (traps heat) |
| Special occasion | Silk, Chantilly lace, velvet | Cotton (lacks visual impact) |
| Travel | Microfibre, cotton blends | Velvet, delicate lace |
| Hot climate | Cotton, mesh, modal | Velvet, heavy satin |
| Bridal | Chantilly lace, silk charmeuse, guipure | Synthetic mesh |
| Gifting | Silk, lace, velvet | Basic cotton |
Lingerie labels list fibres by percentage, from highest to lowest. Here's how to decode common combinations:
The burn test (for verification): Silk burns slowly, smells like burning hair, and leaves a crushable ash. Polyester melts, smells synthetic, and leaves a hard bead.
Fabric is not a detail — it is the product. The right fabric makes a piece feel like it costs three times more than it does. The wrong fabric makes an expensive piece feel cheap.
When you shop for lingerie, read the label, know the fabric, and ask the brand where it came from.
