World KNK makes custom shirts for fashion brands in Bandung, Indonesia: woven shirts cut and sewn to your own patterns, in our own factory, since 2000. Production runs start at 1,000 pieces per style, mixed across your full size run, with 200,000 pieces of monthly capacity behind them. Sampling takes 1 to 2 weeks and bulk delivery 6 to 12 weeks, so a shirt approved this month is on your racks this season.
Private label, made at scale
Most low-minimum shirt sources are sampling shops: brilliant at ten shirts, unreliable at a thousand. Platforms match you with small workshops, and the order that made it through sampling falls apart at grading, or the re-order never matches the sample. We sit on the other side of that gap. Your tech pack or reference shirt becomes a graded pattern, cut digitally on Lectra systems, sewn on the same lines under the same checks, with your labels sewn in. The shirt you approved in sampling is the shirt your customer buys, in every size, in every re-order.
When a style sells and you scale it up, the same factory makes the larger run. No vendor switch, no re-development, no mystery about whether the fit will drift.
What we make for fashion brands
Dress shirts & button-downs
Crisp collars, clean plackets and pattern matching, sewn to your blocks in the cloths your label is known for.
Casual woven shirts
Relaxed and classic fits in flannel, poplin, linen blends and brushed twills, with your trims and labels.
Oversized & statement cuts
Fashion-forward shapes graded carefully, so the look holds across the size run without losing the silhouette.
Shirt sets & co-ords
Matched shirt-and-bottom programmes sewn together, so colours and cloth agree across the set.
Branding in production
Woven labels, embroidery and printed details applied as the shirt is made, not added on top afterwards.
Full size runs, graded properly
Every style graded from XS to the top of your range on the same digital pattern, so the fit holds across the run.
Why brands graduate to us
The usual journey runs backwards. Brands start with a low-minimum workshop for samples and first drops, and the moment a style works, the problems start: re-orders that fit differently, grading that wanders, lead times that slip at exactly the wrong moment. We take the styles that proved themselves and make them properly: the same pattern, industrial consistency, 200,000 pieces a month of capacity, and quality checks between every stage. Your labels go in during production, your packaging requests are followed, and the re-order you place next season matches the sample you approved last season.
How a production run works
Send your tech pack, reference shirt or sketch. Samples are in your hands in 1 to 2 weeks, and the fit is approved on real bodies before bulk is cut. While samples are out, confirm your size breakdown against your sales plan. Bulk production takes 6 to 12 weeks depending on fabric; a custom-developed cloth adds 4 to 8 weeks, so flag it early. Patterns stay on file with the factory: the restock that follows a sell-out is a re-order, not a project.
Custom shirt FAQs
What is the minimum order for custom shirts?
1,000 pieces per style, mixed across your size run. Custom fabric development starts at 1,500 pieces per style.
Can you work from our tech pack?
Yes. Tech packs, reference garments and sketches all work as starting points, and samples are approved before bulk is cut.
Can we use our own labels and branding?
Yes. Woven labels, embroidery and printed details are applied in production, to your placement and specification.
How consistent are re-orders?
Patterns are stored digitally on Lectra systems and cut from the same file every time, so a restock matches the first delivery exactly.
How long does production take?
Sampling takes 1 to 2 weeks and bulk production 6 to 12 weeks. Allow an extra 4 to 8 weeks for a custom-developed cloth.
Do you ship internationally?
Yes. We export from Bandung, Indonesia, and produce for overseas buyers, including a Hawaii-based uniform procurement house.
