- Confirm experience with swim-specific fabrics (chlorine-resistant, four-way stretch, UPF, recycled options).
- Match MOQ to your current stage and budget.
- Request samples to evaluate fit, construction, and quality.
- Ask about lead times, communication style, and private-label extras (labels, hang tags, packaging).
- Verify whether they can scale with you as order volumes grow.
