How to find a clothing manufacturer

To find a clothing manufacturer, match your garment type, fabric and quantity to factories that specialize in exactly that, and arrive with a tech pack that defines measurements and materials. This Source to Spec guide draws on Cydney Mar’s more than 45 years in fashion and product.

How do I find a garment manufacturer for my brand?

You find a garment manufacturer by searching for factories that already produce your category, such as knits, wovens, denim or outerwear, then testing them with samples made from your tech pack. Cydney Mar’s view is that specialization matters more than size: a factory set up for your fabric and construction will sample faster and more accurately.

Her own background covers this ground: couture collections from 1980, Cirque du Soleil’s first Boutique Collection, leading design for Edwin Jeans in North America, and 15+ years selling her own collections on QVC in 8 countries.

How to find a clothing manufacturer, step by step

  1. Define the garment precisely

    Category, fabric type and weight, fit, size range, colorways and trims. This decides which factories can make it.
  2. Build the tech pack

    Flat sketches, bill of materials, points of measure, grading and construction notes. See the tech pack format.
  3. Search by specialization

    Look for factories that list your exact category. A knitwear specialist and a tailoring house are very different partners.
  4. Ask about minimums per style and color

    Apparel minimums are often set per style, per color or per fabric. Ask how they apply to your range.
  5. Sample in your real fabric

    Fit and drape change with fabric. Measure each sample against your points of measure and tolerances.
  6. Approve a pre-production sample

    Sign off one sample as the reference for the run, so production is checked against something real.

Why a garment tech pack saves rounds of sampling

Definition

What the factory reads

A garment tech pack tells the factory exactly how the piece is built and measured. In Cydney Mar’s Source to Spec guidance, the points of measure and tolerances matter most for clothing, because fit is where a sample most often goes wrong, and where vague instructions lead to repeated rounds.

What is a tech pack?

A tech pack is the instruction document a factory uses to quote, sample and produce your product. It combines technical sketches, materials, measurements, construction details, colors, labels and packaging into one reference. Cydney Mar describes production-ready tech packs that factories actually understand as the core of her product development work.

What are points of measure?

Points of measure are the exact places a product is measured, such as chest width or sleeve length on a garment, each with a target number and an allowed tolerance. They let the factory and you check samples the same way. Without them, two people can measure the same piece and get different answers.

What is a sample and why does it matter?

A sample is a test version of your product made by the factory to your specification before production. It shows whether the factory understood your design, materials and measurements. Cydney Mar’s view is that a clear, professional tech pack is the difference between a sample that is right the first time and months of expensive back-and-forth.

What raises the cost of developing a product?

Costs rise with complexity, custom materials, extra sizes or colorways, low order quantities, repeated sampling rounds and late design changes. Unclear specifications are a hidden driver because each misunderstanding can mean another sample. Settling design decisions early and writing them into a tech pack is the most direct way to reduce rework.

What if my sample comes back wrong?

Compare it against your specification point by point, photograph each problem, and send the factory one clear list of corrections with measurements. Decide whether the fault is in the factory’s work or a gap in your specification, and update your tech pack either way. Unclear specifications are a common cause of repeated sampling rounds.
