What can GSM tell you, and what does it leave out?
GSM helps describe the material being considered. It does not specify softness, stretch recovery, shrinkage or opacity on its own. Two fabrics at a similar weight may feel different because their yarns, construction and finishing differ. Compare them in similar lighting and test the same washing conditions.
How do you choose for your intended collection?
| Your priority | What to inspect |
|---|---|
| A substantial silhouette | Structure and how the body hangs |
| Comfort for layering | Hand feel, flexibility and the intended climate |
| A light colour | Opacity in the chosen colour and finish |
| A large graphic | Surface suitability and how decoration changes the feel |
Should an oversized T-shirt always use heavier fabric?
No single weight defines an oversized fit. Pattern measurements create the silhouette; fabric changes how that silhouette behaves. A dropped shoulder, wider body and shorter length need to be evaluated together. Avoid choosing solely from a competitor’s stated GSM.
What should be confirmed in your sample?
If you do not have a weight target, share a physical reference or explain the desired feel. Ask which available materials can be compared. The catalogue photos are visual references; they do not confirm each style’s fabric specification.
- Composition, target weight and agreed production tolerance.
- Neck rib, seam construction and shape retention.
- Measurements before and after the agreed wash check.
- Artwork appearance and hand feel on the selected fabric.
These guides explain choices to discuss. Catalogue photos are visual references; final materials, measurements, MOQ, prices and schedules are confirmed in your brief, sample and quotation.
