Straight Jean Customization Program for Railway and Transit with Acid Wash
Straight Jean Customization Program for Railway and Transit
This programme covers the full path from a straight jean concept to repeatable bulk supply for railway and transit. The build starts from everyday-casual references — straight jean in organic cotton — then locks fabric weight, wash behaviour and fit tolerance so every reorder matches the approved sample.
Most straight jean buyers arrive with one of these problems: colour faded after a few washes, or the previous supplier could not hold consistency on reorders. The fix is a written spec before bulk: shrinkage allowance, stitch density, colour tolerance and a golden sample kept at the factory.

Quality control
Every bulk lot is compared against the approved sample for shade, hand feel, measurements and wash behaviour. Straight Jean reorders stay comparable over time because the spec, the lab dip and the golden sample are all on file.
FAQ
What is the minimum order quantity?
Standard programmes start at 800 pieces per style and colour. We can split sizes across a size set, and for first orders we often accept a mixed-colour run to help you test the market.
How is shipping handled?
We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.
What file formats do you need for artwork?
Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.
Can you match a specific colour?
Yes. Send us a Pantone TCX reference or a physical swatch. We return lab dips for approval and hold bulk shade within the agreed tolerance band before cutting.
