HOW WE WORK

From brief to shipment.

Our team works directly with you and agrees the production details with you before cutting begins.

  1. Brief & materials

    Send us your tech pack or reference garment. We review the fit, fabric, colours and quantities with you.

  2. Sampling

    We develop a sample so you can check fit, fabric and finish before approving production.

  3. Cutting & sewing

    We cut and sew in-house using the approved sample as the production reference.

  4. Checks & dispatch

    We check the finished garments, then pack the order and prepare it for dispatch.

The standard behind Made in Portugal

Portugal has earned its place in high-end garment manufacturing through decades of textile expertise. In Barcelos, we use the approved sample as our production reference and check the finished garments before packing.

The people behind each order

We value fair working conditions for our team and choose suppliers and production partners we trust to share that commitment. You work directly with the team that oversees production in Barcelos.

BEFORE YOU START

Frequently asked questions

Do I need a tech pack?

A tech pack helps us quote. You can also start with a reference garment, photos or a sketch. Tell us the fit, fabric and quantities you have in mind.

Can I approve a sample first?

Yes. We develop a sample for you to review the fit, fabric and finish before approving bulk production.

What are the minimum quantities and lead times?

They depend on the style, fabric, colours and order size. Share your quantities per colour and target date so we can confirm what is possible.

Can I add my own branding?

Yes. Tell us which labels, prints or embroidery you need and send your artwork if you have it. We can check the options for your garment.
