A guide to lingerie fabrics and materials

The fabric of a lingerie piece determines more than how it looks. It determines how it moves against skin, whether it breathes in warm conditions, how it holds its shape over time, and how much care it requires. Two chemises at similar prices may look comparable in a photograph and feel entirely different in wear — because one is 19-momme mulberry silk charmeuse and the other is polyester satin with a satin-weave finish.

This guide maps the main fabric families used in fine lingerie, explains what each actually is (not as marketing language, but as material fact), and gives you the vocabulary to assess what you are buying and whether it is suited to what you need. It also flags the places where the terminology is consistently misleading — "satin" is a weave, not a fibre; "silk" on a care label can mean many things — so you can navigate confidently.

Silk: the fibre and its variables

Silk is a natural protein filament produced by the Bombyx mori silkworm as it spins its cocoon. The filaments are reeled from the cocoon, spun or woven into yarn, and then woven or knitted into fabric. The resulting material is lightweight, temperature-regulating, moisture-wicking, and has a distinctive lustre that polyester fibre cannot replicate precisely because the lustre of silk comes from the triangular cross-section of the filament, which refracts light at multiple angles simultaneously.

The key variable within silk is momme weight — the weight of the fabric in pounds per 100 yards of 45-inch-wide cloth. A higher momme number means a heavier, more opaque, more durable fabric.

6–8 momme: very sheer, used for chiffon overlays and fine veiling. Not suitable as a standalone garment.
12–14 momme: the typical range for slip-weight silk, charmeuse, and light pyjama tops. Wearable as a solo layer.
16–19 momme: the ideal range for lingerie and sleepwear. Substantial enough to hold structure, fine enough to drape.
22+ momme: heavyweight silk used in robes, pyjama sets, and travel pieces intended to last for years.

Momme weight is rarely printed on the label. For how to identify it from product descriptions and what to look for, see what momme weight means in silk fabric.

Satin and charmeuse: the weave distinction

"Satin" is a weave structure, not a fibre. A satin-weave fabric is one in which the warp threads float over several weft threads before passing under, creating a smooth, lustrous face. This structure can be applied to silk, polyester, acetate, or any other fibre.

Silk satin and polyester satin feel significantly different. Silk satin is cool to the touch, temperature-regulating, and moves with the body. Polyester satin is warm to the touch, non-breathable, and has a heavier sheen that many people associate with lingerie but which is actually a characteristic of synthetic fibre rather than quality.

Charmeuse is a lightweight satin-weave fabric — typically silk, though again the term has been applied to polyester. It has more drape than standard silk satin because of the lighter weight and the particular floating structure of the weave. A 16-momme silk charmeuse camisole will move differently from a 19-momme silk satin one: both are silk, both are satin-weave, but the hand and drape are noticeably different.

Lace: woven, knitted, and the French distinction

Lace is not a single material but a family of open-mesh structures. For lingerie purposes, the main variants are:

Calais-Caudry lace, made in the Nord-Pas-de-Calais region of France, is considered the benchmark for quality in woven lace. It is produced on Leavers lace machines — 19th-century mechanical looms that produce a structure closer to hand-pillow lace than any other industrial method. The yarn is typically long-staple cotton, and the construction is dense enough to be used as a principal fabric rather than only as trim.

Stretch lace is a knitted construction with elastane. It has a different feel — more elastic, less structured — and is the typical construction for lace briefs, bralettes, and body pieces where movement and recovery are more important than precise form. It is more durable under machine-washing than woven lace.

Appliquéd lace uses lace motifs bonded or stitched onto a different ground fabric. The quality of the result depends entirely on the quality of the lace itself and the skill of the application.

Modal and cotton: the everyday fibres

Modal is a semi-synthetic cellulosic fibre derived from beech wood pulp. It is softer than cotton, has a finer filament, and resists pilling under repeated washing better than standard cotton. Its stretch recovery is good in jersey constructions. It is widely used in everyday bralettes, briefs, and soft sleepwear because it combines the breathability and feel of a natural fibre with the wash durability of a synthetic.

Cotton in fine lingerie is most commonly found in cotton-lawn or fine voile constructions — lightweight, densely woven fabrics that are breathable, crisp, and well-suited to warm-weather sleepwear. Long-staple cotton (Egyptian or Pima) in these constructions has a notably finer hand than standard-staple cotton and holds its structure across many washes.

The comparison between modal and cotton for everyday wear is addressed directly in modal versus cotton for everyday lingerie comfort.

Tencel and emerging cellulosic fibres

Tencel (branded lyocell produced by Lenzing AG) is a closed-loop cellulosic fibre made from eucalyptus pulp. The production process recycles 99 percent of the solvent used, making it one of the more environmentally defensible fibres in the supply chain. Its feel is smooth, with a slight silkiness; it is moisture-wicking; and its skin-pH neutrality makes it one of the better-evidenced choices for people with skin sensitivities.

For a detailed assessment of Tencel's properties in lingerie — including where the dermatological evidence is strong and where claims are overstated — see is Tencel a good fabric for sensitive skin lingerie.

Natural fabrics for sensitive skin

For people with chronic skin sensitivity or conditions such as eczema or contact dermatitis, fabric choice is not a matter of preference but of wearability. The fibres with the best evidence base for sensitive skin are mulberry silk (moisture-regulating, protein-based, smooth filament with no abrasive surface), modal (pH-neutral, smooth surface, hypoallergenic under most testing conditions), and Tencel lyocell (closed-loop production, smooth filament, neutral pH).

The full account is in natural fabrics for sensitive skin lingerie, which includes a note on synthetic lace overlays and their effect on breathability even when the main garment is a natural fibre.

Slips, chemises, and the vocabulary of unstructured pieces

A slip is an underlayer garment, typically cut straight and hemmed at or below the knee, worn primarily beneath a dress or skirt for static control and coverage. A chemise is a standalone garment, cut with more design intentionality — typically shorter, often bias-cut, and treated as lingerie rather than solely as a functional underlayer.

The distinction matters for both sizing and care: a slip is usually sized and constructed for function, a chemise for experience. The specific comparison is in the difference between a slip and a chemise, and the choice between a slip dress and a full slip in slip dress versus full slip: how to choose.

How to identify real silk from synthetic satin

The practical skill of distinguishing mulberry silk from polyester satin is relevant when shopping in person — at a boutique, a market, or when assessing a vintage piece. Three methods work reliably:

The burn test: a few threads of real silk burn slowly, smell like burning hair, and leave a crushable ash. Polyester melts and smells of burning plastic.

The ring test: real silk pulled through a ring meets minimal resistance; a polyester fabric of equivalent weight bunches and catches.

The touch test: silk is cool to the touch and warms quickly against the skin. Polyester feels warmer at first contact.
