Custom T-Shirt Manufacturing for Clothing Brands

Greyfin Sports works with clothing brands, startups, streetwear labels, teams, retailers and other B2B buyers that need custom T-shirts manufactured to their own specifications. The final garment is developed around the approved fit, measurements, fabric requirements, neckline, colors, branding and packaging rather than supplied as a fixed retail product.

Buyers can send a tech pack, measurement chart, sketch or clear reference images to start the discussion. If the design is still being developed, identify the fixed requirements and the details that need review during sampling.

Fit, Sizing and Garment Construction

A T-shirt should be specified by measurements rather than generic size names alone. Buyers can define body length, chest width, shoulder width, sleeve length, neckline shape and other relevant points according to the intended fit.

Construction details such as sleeve shape, neck rib, hem finish and panel requirements should be documented in the production brief or approved sample before bulk manufacturing.

Fabric Requirements

Fabric selection can be discussed around composition, GSM or weight, hand feel, stretch, structure, surface finish and intended use. If the exact material is not yet selected, explain the result you want so suitable options can be reviewed during development.

For more information about fabric selection, pattern development, cutting and stitching, visit our custom apparel manufacturing capabilities page.

Printing, Embroidery and Artwork Placement

Custom T-shirt projects can include buyer-supplied logos, graphics and approved artwork placements. Depending on the fabric and design, suitable decoration methods can be discussed for the project.

Artwork dimensions, placement, colors and final production files should be confirmed before bulk production so the approved sample can act as a clear reference.

Private Label Options

For private label collections, garment branding can include approved neck labels, size labels, care labels, hang tags and packaging. These requirements should be included in the initial product brief so they can be reviewed together with the garment specification.

Sample Development

A development sample allows the buyer to review fit, measurements, fabric, construction, color, decoration and label placement before larger quantities are produced. Requested revisions should be documented clearly and incorporated into the final approved production specification.

Sampling terms, production quantity and commercial details are confirmed according to the specific project after the requirements are reviewed.

International Manufacturing Support

Greyfin Sports serves overseas clothing brands and business buyers as an international custom apparel manufacturing partner. We do not represent the business as a USA factory. USA and other international buyers can discuss custom T-shirt production according to their approved specifications and order requirements.
