The price tag does not tell you. I have seen PKR 80,000 suits labelled "pure silk" that were Chinese satin blends, and I have seen beautifully honest mid-range pieces in genuine sheesha silk where the brand simply charged less than they could have. The only way to know what fabric you are wearing - and more importantly, what you are investing in - is to learn what to look for before the receipt is signed.
Pure silk and synthetic silk perform very differently over time. Touch, temperature response, burn behaviour, and drape each tell part of the story - no single test is conclusive on its own. For Pakistani formal wear, where fabric is the primary investment, learning to read these signals is the difference between a piece that lasts a decade and one that dulls after two seasons. Sheesha silk, the fabric in La Soie's Abresham line, is a pure silk woven with mirror-work. It has specific characteristics that distinguish it from synthetic alternatives once you know what to feel for.
What "silk" actually means in Pakistani fashion
In Pakistani retail - and particularly in the formal and ready-to-wear market - the word "silk" covers a wide range of fabrics, only some of which are genuinely natural silk. Pure silk is a protein fibre produced by silkworms. Synthetic silk is a broad category including polyester satin, rayon, viscose, and blended fabrics engineered to mimic silk's surface sheen. The confusion is sometimes deliberate, sometimes innocent, but the result for the buyer is identical: you need your own verification method.
The fabrics commonly labelled "silk" in Pakistani fashion
Sheesha silk is pure mulberry silk woven with small glass mirrors - the mirrors are structural, part of the weave itself, not appliquéd onto the surface. Shamoz is a heavier pure silk with a structured, lustrous drape. Medium silk is a lighter pure silk used widely for dupattas. Korean silk is a polyester satin that mimics pure silk's surface - it is the most common synthetic in the premium formal market. These fabric names matter: a brand that uses them precisely is more likely to be dealing honestly with fabric sourcing.
Where synthetic enters the market
I hear from clients regularly that they paid a strong price for what they were told was pure silk and received something that felt right on the hanger but behaved completely differently after the first event - pilling, losing sheen, developing static in a warm room. This is not always deliberate fraud; sometimes the retailer genuinely does not know their supplier's fabric composition. But the practical consequence for the buyer is the same. The responsibility to verify falls to you.
How to tell by touch and temperature
The fastest test is temperature: hold the fabric flat against the inside of your forearm for three seconds. Pure silk warms to your skin temperature almost immediately - it feels like a second skin within moments. Synthetic silk stays cooler for longer, sometimes carrying a slight clamminess. This difference is subtle at first encounter but becomes unmistakable once you have held genuine sheesha silk against skin. It is the same quality that makes pure silk genuinely comfortable in Pakistan's heat in a way that polyester never is.
What the ring test actually shows
The ring test - drawing fabric through a finger ring to assess how it gathers - tells you about fineness and weave density, not fibre composition. A fine polyester satin passes through a ring just as cleanly as fine pure silk. This test has circulated widely in Pakistani fashion communities as a silk identifier and it is not reliable for that purpose. It is useful for assessing weave quality: coarse threads, uneven density, and badly finished edges all show up. For natural-versus-synthetic identification, however, it tells you nothing definitive.
Drape and structure as signals
Pure silk has a weight-to-drape relationship that synthetics have not replicated convincingly. It is heavier than it appears when hanging and falls with a controlled fluidity - not stiff, not limp. Polyester satin tends toward stiffness; cheap viscose blends are overly fluid and lose structure entirely against the body. Sheesha silk specifically has a slightly structured fall because of the woven mirrors - it holds a silhouette. If a fabric labelled sheesha silk collapses against the body with no structure, look more carefully at its composition.
The burn test - the only definitive check
The burn test is the only method that conclusively distinguishes natural from synthetic fibre. It requires destroying a small section of fabric, which makes it impractical for finished garments. For unstitched fabric, or when a retailer offers you a sample thread from a thaan before you commit to a purchase, it is the test to use. In Karachi's fabric markets - and in the fabric sections of Liberty Market in Lahore - credible vendors will give you a thread without hesitation. A refusal to provide a sample should be noted.
How to conduct it safely
Pull two or three threads from the fabric's hem allowance or a seam allowance. Hold them with tweezers over a non-flammable surface. Bring a lighter flame to the threads for one to two seconds, then remove the flame immediately. Observe whether the material continues to burn on its own. Pure silk self-extinguishes almost immediately after the flame is removed. Synthetics often continue burning or melting after the flame source is gone. Then press the residue between your fingers.
Reading the residue and smell
Pure silk leaves a crushable black ash that crumbles to powder and smells unmistakably of burning hair - it is a protein fibre, the same molecular structure as your own hair. Polyester leaves a hard, fused plastic bead and smells of burning plastic. Rayon smells faintly of paper. The smell alone is reliable enough that experienced tailors in Karachi use it routinely when sourcing fabric before buying a full thaan. According to APTMA's textile classification framework, natural protein fibres have distinctly different combustion profiles from synthetic fibres, making the burn test a standard verification method across the industry.
Price as a signal - and its limits
Price is a minimum threshold filter, not a verification. In my experience, genuine sheesha silk formal suits below PKR 35,000 are rare - the raw material and production costs make it difficult to reach that price point honestly. But a suit priced at PKR 60,000 is not automatically pure silk. Use price to rule out fabric that is almost certainly synthetic (anything labelled "pure silk" at PKR 15,000 is not pure silk), but do not rely on price alone to confirm what you are buying.
| Property | Pure silk (sheesha, shamoz) | Synthetic silk (Korean silk, polyester satin) |
|---|---|---|
| Temperature response | Warms to skin within 2-3 seconds | Stays cool; may feel slightly clammy |
| Burn residue | Crushable black ash, hair smell | Hard fused bead, plastic smell |
| Drape | Controlled, structured, holds silhouette | Stiff (polyester) or overly fluid (viscose) |
| Long-term sheen | Deepens with careful wear and storage | Dulls; polyester may develop static |
| Breathability | High - regulates body temperature well | Low - traps heat and moisture |
| Typical price (PKR) | 35,000 and above | 15,000 to 50,000 |
What it means when buying Pakistani silk online
Online shopping for Pakistani formal wear is where this knowledge is most practically useful, because you cannot hold the fabric before buying. Three things compensate: the brand's vocabulary about fabric composition, the specificity of care instructions, and the brand's exchange policy. Brands that use precise fabric terminology - "pure mulberry silk", "sheesha silk woven with glass mirror inserts" - are more likely to be sourcing honestly. Vague terms like "premium silk" or "silk-feel finish" should be treated as synthetic until proven otherwise. As The News has noted in coverage of Pakistan's fashion industry, transparency in fabric labelling remains inconsistent across the market, which places the verification responsibility with the buyer.
Reading care labels as a final check
Once a garment is in hand, the care label is definitive. Pure silk is labelled "dry clean only" or "hand wash cold, lay flat to dry" - it cannot tolerate machine washing or high heat. If a garment labelled "pure silk" carries care instructions that permit machine washing or tumble drying, it is not pure silk. This applies consistently across every market: the care requirement is set by the fibre, not the brand.
Frequently asked questions
Is Korean silk real silk?
No. Korean silk is a polyester satin with a smooth surface that mimics pure silk's sheen. It is a good quality synthetic and is used honestly by many Pakistani formal wear brands, but it is not a natural fibre. The name is a trade term used in the Pakistani market, not a silk-origin designation.
Can sheesha silk be washed at home?
Sheesha silk should be dry cleaned. The woven mirrors are secured within the silk weave, and home washing risks loosening them and distorting the fabric. For full guidance on caring for silk and embroidered pieces, see our guide to Pakistani outfit care and long-term preservation.
How does sheesha silk differ from regular pure silk?
Sheesha silk is pure mulberry silk woven with small glass or metal mirrors during production. The mirrors are structural - integrated into the weave rather than attached afterwards. This gives sheesha silk its characteristic light-catching quality and adds a slight weight that plain pure silk does not have. It also changes the care requirements, which is why dry cleaning is particularly important for sheesha silk pieces.
Is the burn test safe to perform on finished garments?
Not practically. The burn test requires removing fabric threads, which risks visible damage to a finished garment. For garments already in hand, use the temperature test, the drape assessment, and the care label check together. The burn test is most reliable when buying unstitched fabric from a market, or when a retailer can provide a sample thread before you commit to a full purchase.
What does pure silk look like after several years?
Properly stored and dry-cleaned pure silk deepens slightly in lustre over years of careful wear. The fibre is durable when treated correctly - there are sheesha silk pieces in Pakistani wardrobes that are fifteen to twenty years old and still worn for formal occasions. Synthetics do not age in the same way: polyester dulls and may develop permanent static; viscose blends may thin at points of friction.
The Abresham Embroidered collection is entirely sheesha silk - each piece with the fabric, mirror construction, and occasion context specified. The Abresham Printed line works across sheesha silk and pure georgette. Both are at lasoiepk.com.
