Two fabrics can share a fibre and a weave and still be wrong for each other’s garments. The difference is in weight (how heavy), drape (how it falls) and hand (how it feels). These three words are how tailors talk about fabric.
What you’ll learn
- What GSM and momme mean, and rough weight bands.
- How to judge drape and body in the shop.
- The words for hand, and what they tell you.
- How to match weight and drape to a design.
Weight
Weight is usually given as GSM – grams per square metre. Silk is sometimes given in momme (mm), a Japanese unit; 1 momme is about 4.3 GSM.
| Band | Rough GSM | Examples | Good for |
|---|---|---|---|
| Very light | Under 60 | Chiffon, organza, fine mulmul | Dupattas, overlays, sleeves |
| Light | 60–120 | Voile, cambric, georgette, Mysore crepe | Kurtas, blouses, sarees, shirts |
| Medium | 120–200 | Poplin, rayon, raw silk, linen | Dresses, trousers, kurtas, jackets |
| Heavy | 200+ | Drill, denim, velvet, brocade, suiting | Trousers, jackets, lehengas, sherwanis |
These bands are rough. Most shops in India do not state GSM; online sellers often do. If you can’t get a number, compare by hand with a fabric you know.
Drape and body
Drape is how a fabric falls under its own weight. Body is how well it holds a shape. They pull in opposite directions:
- Fluid, low body – georgette, chiffon, crepe, rayon, jersey. Falls close to the body in soft folds; good for anarkalis, sarees, gowns and palazzos.
- Medium – cotton cambric, linen, Chanderi, Mysore silk. Soft but holds a line; kurtas, shirts, blouses.
- Crisp, high body – organza, taffeta, raw silk, brocade, drill. Stands away from the body; structured blouses, lehengas, jackets, puffed sleeves.
The drape test in the shop
- Unroll about half a metre and hold it up by one corner. Watch how it falls: in a straight curtain, in soft folds, or standing out.
- Gather it in your hand and let it fall. Does it spring back, or hang limp?
- Drape it over your arm or shoulder in front of a mirror. Imagine it as the garment.
A quick rule: light and fluid for movement, medium for everyday shape, crisp or heavy for structure and volume.
In more depth: the words for hand
- Soft / harsh – how it feels against the skin.
- Crisp / limp – how much it resists bending.
- Smooth / textured – surface; slubs, crepe, pile.
- Dry / slippery – linen feels dry; satin slippery.
- Cool / warm – cool at first touch suggests natural fibres.
- Full / thin – a full hand has substance even if light.
Opacity
Hold the fabric against your hand under a light. If you can see your skin clearly, it will need a lining or a slip for most garments. Light colours are more see-through than dark ones of the same weight.
Matching fabric to a design
A design sketch implies a fabric. A flared anarkali needs drape; a puffed sleeve needs body; a pleated trouser needs medium weight with a good press. When a customer brings a picture, ask: “Is it falling, or standing?” Then choose the fabric that does that.
Tips, tricks and hacks
- Weigh a known piece. A kitchen scale and a 10 × 10 cm square give you GSM: grams × 100.
- Add body without changing fabric. An interfacing, an underlining or a stiffer lining gives structure to a soft fabric (Module 5).
- Reduce body. Wash crisp cotton or use a soft lining for a gentler fall.
- Pair weights carefully. A heavy border on a light saree body can drag; ask how it is finished.
- Remember the lining weight when judging the final drape.
- Bias adds drape. The same fabric cut on the bias falls more softly.
Common misunderstandings
“Heavier means better quality.”
Fine mulmul is light and luxurious. Weight suits a purpose, not a quality level.
“Starch shows the real hand.”
Many shop fabrics are starched or sized. The true hand appears after the first wash.
For earning and teaching
For earning: the most common reason a garment “doesn’t look like the photo” is the wrong drape. Asking “falling or standing?” before the customer buys fabric prevents it.
For teaching: hang five fabrics side by side over a rail and ask learners to rank them from fluid to crisp. Then reveal the GSM.
Drape and weight by garment
| Garment | Drape | Weight |
|---|---|---|
| Saree | Fluid to medium | Very light to medium |
| Structured blouse | Medium to crisp | Light to medium |
| Straight kurta | Medium | Light to medium |
| Anarkali | Fluid | Light |
| Lehenga | Medium to crisp | Medium to heavy |
| Trousers | Medium | Medium to heavy |
| Jacket, sherwani | Crisp | Heavy |
Problems and how to fix them
The garment looks limp compared with the photo
- Add an underlining or interfacing.
- Change to a stiffer lining.
- Prevention: ask “falling or standing?” before buying.
The fabric is see-through once made up
- Add a lining or underlining in a skin-tone or matching colour.
- Wear a slip.
- Prevention: do the hand-behind test in the shop.
Sources and uncertain points
- GSM bands are rough and vary between sources; treat them as a guide.
- The momme conversion (about 4.3 GSM) is the usual approximation.
Check yourself
- Do you know what GSM means?
- Can you do the drape test in a shop?
- Can you name a fluid fabric and a crisp fabric?
- Can you work out GSM with a kitchen scale?
