5. How V-Trust Helps You Control the Quality of Underwear & Swimwear

V-Trust ensures consistent quality and compliance for underwear and swimwear products throughout the entire production process. Our comprehensive inspection services—including Sample Check, Production Monitoring, During Production Inspection, Pre-Shipment Inspection, and Container Loading Supervision, —help you minimize defects, meet international standards, and deliver comfort and safety to your end users.

Sample Check

We evaluate underwear and swimwear samples in our lab, checking critical aspects such as stitching quality, elasticity, fabric GSM, shrinkage rate, and overall workmanship. This helps you assess supplier reliability before full-scale production begins.

Production Monitoring

Our inspectors monitor on-site production daily to ensure product consistency and catch early-stage issues like poor stretch recovery, misaligned patterns, uneven seams, or color inconsistencies. This real-time service supports factory optimization and ensures a stable production flow.

During Production Inspection

Conducted when at least 10% of the order is completed, this inspection focuses on identifying issues such as incorrect sizing, loose straps, label errors, or garment deformity early in the process—reducing rework risks and ensuring timely delivery.

Pre-Shipment Inspection

At the final stage of production, we conduct a full inspection to verify:

• Overall quality and compliance with order specifications
• Fit and stretch test results, stitching, and fabric integrity
• Fabric type and trim verification (e.g., lining, cups, elastic bands)
• Packaging condition, labeling accuracy, and folding presentation

Container Loading Supervision

We ensure underwear and swimwear products are carefully loaded into clean, dry containers, properly stacked to avoid deformation, and securely packed to minimize transit damage—ensuring your goods arrive in excellent condition.
