SeamFoundry
Streetwear Brands — custom manufacturing

For streetwear & fashion startups

Your first drop, done properly

Heavyweight fabrics, true oversized blocks, garment dye and custom neck labels — the details that separate a real brand from printed blanks. From 25 pieces per style, so your first drop doesn't need investor money.

In short

We manufacture cut-and-sew streetwear — heavyweight hoodies, oversized tees and varsity jackets — for new brands from 25 pieces per style, with custom labels, garment dye and retail-ready packaging. Samples take 7–10 days and the cost is credited against your bulk order.

01

Cut-and-sew, not printed blanks

Your fit, your fabric weight, your labels — from 25 pieces. Nobody else at the pop-up is wearing the same blank as you.

02

Heavyweight everything

450+ GSM fleece, 240+ GSM tees, dense embroidery and high-density prints. The handfeel your customers judge in the first three seconds.

03

Retail-ready out of the box

Woven labels, hang tags, polybags and packaging done in production — your drop arrives ready to ship to customers, not ready for a second vendor.

Questions we hear from streetwear brands

I only have a logo — is that enough to start?
Yes. Our design team turns logos and reference images into full production designs at no cost. You approve everything before sampling.
Can I mix sizes and colourways within the minimum?
Within one style, yes — spread your 25+ pieces across sizes, and colourways can often be split at slightly higher totals. Ask in your quote.
What about samples before the full run?
Sampling takes 7–10 days and the cost is credited against your bulk order. Most founders sample 1–2 styles, then launch.
