Our MOQs are structured by production route. For our Core Stock & Configured Stock programmes, MOQs start from 50–100 units per style. For custom ODM and full bespoke OEM development, standard factory production runs start from 200–300 units per style (shared across sizes). Flexible lower-volume capsule options are available through our UK and European boutique partner ateliers.
A typical cycle runs 6–10 weeks: 2–3 weeks for proto samples, 1–2 weeks of fit review and revisions, then 2–3 weeks for size sets and pre-production samples. Simple carry-over styles can be faster; complex tailoring or new fabric development can take longer.
Yes. We review your tech packs for completeness, flag missing measurements or construction details, and can source from your nominated mills or trim suppliers. Where needed we update the pack so factories receive one clear, production-ready specification.
Every order follows a staged QC plan: inline checks during sewing, a pre-final inspection at 20–30% packed, and a final random inspection to AQL 2.5 before shipment. Reports with photos and measurement sheets are shared with you at each stage.
We work on FOB, CIF and DDP terms and can arrange sea, air or courier freight. Our logistics partners handle export documentation, customs clearance and delivery to your warehouse, retail stores or 3PL.
Partner factories are audited and hold recognised certifications such as BSCI/amfori, SEDEX/SMETA, WRAP, OEKO-TEX Standard 100 and GOTS for organic programmes. Current certificates are available on request for every production route.
