# The Math of Motion: How Fabric GSM Defines the Drape of Sequin Textiles
In the B2B fabric world, "weight" is not just a shipping metric; it is a design parameter. For a sourcing manager, understanding the relationship between **Grams per Square Meter (GSM)** and the final garment's drape is the difference between a high-fashion success and a retail failure.
At **Yunfan Textile**, we’ve cataloged the physical movement of our entire 2027 collection. Here is your technical guide to GSM selection.
## 1. Lightweight (80-150 GSM)
- **Texture**: Fluid, airy, and high-motion.
- **Base**: Typically 20D or 30D nylon mesh.
- **Best For**: Scarf overlays, light bridal veils, and summer party dresses.
- **Sourcing Tip**: Pair with 2mm micro-sequins to maintain the fabric's buoyancy.
## 2. Medium Weight (150-250 GSM)
- **Texture**: Balanced, stable, and versatile.
- **Base**: 40D polyester mesh or soft chiffon.
- **Best For**: High-street fashion gowns, tailored blazers, and evening wear.
- **The Standard**: This is our most requested weight for wholesale orders.
## 3. Heavyweight (250+ GSM)
- **Texture**: Structured, sculptural, and low-motion.
- **Base**: 50D reinforced mesh or heavy velvet.
- **Best For**: Upholstery, commercial curtains, and varsity jackets with 3D puff embroidery.
