Quick Answer
Fabric approval should move from swatch review to color confirmation, sample garment testing, bulk fabric confirmation and pre-production sample approval. A swatch alone is not enough for private label leggings because opacity, recovery and fit must be checked in the finished garment.
Stage 1: Fabric Swatch Review
The buyer first reviews hand feel, stretch, recovery, color direction and rough GSM. This stage narrows the fabric direction but does not approve bulk production by itself.
Stage 2: Lab Dip or Color Confirmation
For custom colors, lab dip approval helps align the target shade before bulk dyeing. Buyers should confirm acceptable color tolerance and lighting conditions.
Stage 3: Sample Garment Testing
A sewn sample shows how the fabric behaves with pattern, waistband, seams and logo method. Opacity and recovery should be reviewed on body.
Stage 4: Bulk Fabric Confirmation
Before cutting bulk, buyers may need to confirm bulk fabric lot, color and hand feel against the approved reference. This is especially important for reorders and custom colors.
Stage 5: Pre-Production Sample Approval
A pre-production sample connects material, pattern, logo, labels and packaging into one reference. It should be kept for final inspection comparison.
Buyer Approval Checklist
The buyer should record approvals for swatch, lab dip, sample garment, logo, labels, packaging and inspection standard.
