Fabric & hand feel

Share composition, weight and hand-feel references if you have them. We can discuss the missing specifications.

Fit & neckline

Set the shoulder line, body width, sleeve and length. Review the neckline with the rest of the garment.

Artwork & placement

Confirm artwork size, placement and the intended decoration. Specific techniques are assessed for your project.

Custom T-shirt manufacturing for small brands

SEASANG is a T-shirt manufacturer in Humen, Dongguan. We cut and sew custom T-shirts for independent clothing brands, from regular fits to boxy, oversized and heavyweight tees. Most projects start at around 100 pieces per style, per colour.

A good tee comes from three decisions: the fabric, the fit and the artwork. Heavyweight tees are usually 240–300 gsm cotton jersey; everyday tees are lighter. Tell us the body width, length, shoulder drop, sleeve and neckline you want, plus the artwork size, placement and decoration method. We confirm everything on a physical sample before bulk.

Starting quantity
~100 pcs per style, per colour; sizes split within that
Sample
7–10 days, depending on construction
Bulk production

What GSM is a heavyweight T-shirt?

Heavyweight streetwear tees are usually 240–300 gsm. Send a reference tee or the weight you want and we confirm the fabric on the sample.

Can you make an oversized, boxy fit?

Yes. Give us the body width, length and shoulder drop you want, or send a reference tee, and the sample is built to those measurements.

What is your MOQ for custom T-shirts?

Around 100 pieces per style, per colour, with sizes split inside that number.

From reference to sample.
