Oversized Shirt Customization Program for Running and Marathon Events with Seam Sealing
Oversized Shirt Customization Program for Running and Marathon Events
This programme covers the full path from a oversized shirt concept to repeatable bulk supply for running and marathon events. The build starts from everyday-casual references — oversized shirt in corduroy — then locks fabric weight, wash behaviour and fit tolerance so every reorder matches the approved sample.
Most oversized shirt buyers arrive with one of these problems: wholesale costs squeezed the retail margin, or the fit drifted between sizes. 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. Oversized Shirt reorders stay comparable over time because the spec, the lab dip and the golden sample are all on file.
FAQ
Do you provide compliance documents?
We can arrange OEKO-TEX, GOTS, BSCI, WRAP and ISO documentation as well as third-party testing reports for WRAP, and we support REACH, CPSIA and Prop 65 declarations for the relevant markets.
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.
What is the minimum order quantity?
Standard programmes start at 200 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.
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.
