DEVELOPMENT PROCESS
A Clear Path from Product Idea to Bulk Order
The fastest projects begin with complete specifications. We identify missing information early so sampling and costing are based on the same target.
Style, fit, fabric, colors, sizes, quantity, branding, packaging and target market.
Material confirmation, pattern review and custom sample development.
Confirm fit, measurements, workmanship, colors, labels and packaging.
Bulk production, inspection, packing and shipment under confirmed specifications.
PRODUCTION & QUALITY CONTROL
Control the Details Before They Become Inventory Problems
Approved specifications guide bulk production. Checks can include incoming material review, measurements, sewing workmanship, label and waistband position, color or print consistency, needle detection and packing verification.
Typical bulk lead time is around 60 days; peak-season or custom-material projects may require 60–75 days. Timing begins after specifications, sample, payment and production documents are confirmed.
FOB, CIF and DDP shipping options can be reviewed according to destination, order size and delivery requirements.
