From Sketch to Store: How Apparel Production Actually Works
You have the vision. You've sketched the pieces, built the mood board, and maybe even picked out your brand name. But then comes the question that stops most aspiring fashion founders in their tracks:
How does a design actually become a finished garment on the shelf?
The apparel production process can feel overwhelming, especially if you're new to the industry. There are tech packs, grading, sourcing, sampling, and production runs to navigate. Without the right partner, it's easy to waste time, money, and momentum.
At Outsourced Fashion Consulting (OFC), we've helped brands across every category, from streetwear to activewear to denim, go from first sketch to finished product. In this guide, we're breaking down the entire apparel production process so you know exactly what to expect.
Step 1: Design & Concept Development
Every great garment starts with a clear concept. Before anything goes to production, your design needs to be fully developed, and that means more than a sketch.
What this step involves:
Finalizing your design aesthetic and target customer
Creating detailed flat sketches (front, back, and any detail views)
Defining colorways, the specific color combinations for each style
Identifying fabric types, weights, and construction details
This is where a lot of brands rush. The more detail you define upfront, the fewer costly revisions you'll face later. At OFC, we work with clients during this phase to make sure every design decision is production-ready before moving forward.
Step 2: Sourcing Fabrics & Materials
Once your concept is locked in, the next step is sourcing the materials that will bring your garment to life. Fabric sourcing is both an art and a science, and the right choice makes a massive difference in quality, cost, and production timeline.
Key sourcing considerations:
Fabric composition (cotton, polyester, spandex blends, etc.)
Weight and hand feel
Minimum order quantities (MOQs) from fabric suppliers
Lead times for fabric production and delivery
Trims: zippers, buttons, drawstrings, labels, patches
At OFC, we have established relationships with trusted fabric suppliers and mills, which means faster turnaround times, better pricing, and access to premium materials that independent brands often can't source on their own.
Step 3: Tech Packs, Your Production Blueprint
With your materials identified, it's time to build your tech pack. A tech pack is one of the most critical documents in apparel production. Think of it as the blueprint your manufacturer uses to build your garment. Without it, production falls apart.
A complete tech pack includes:
Technical flat sketches with measurements
Bill of Materials (BOM), covering every fabric, trim, label, and hardware detail
Construction notes and stitch specifications
Size grading and fit guidelines
Colorway breakdowns
Care label and labeling requirements
Factories rely on tech packs to produce accurate samples and production runs. A vague or incomplete tech pack is one of the leading reasons brands receive samples that look nothing like their vision.
Pro tip: If you don't have an in-house designer or technical specialist, OFC can build your tech packs from scratch.
Step 4: Pattern Making & Grading
With your tech pack and fabrics in place, the next step is pattern making. A pattern is the template used to cut your fabric pieces before sewing.
Pattern making requires precision. Even minor errors at this stage translate directly into fit issues on the finished garment, which is why working with an experienced pattern maker is non-negotiable.
What happens in this step:
A master pattern is created for your base size (typically a size medium or size 8)
The pattern is graded, scaled up and down, across your full size run
A fit model or dress form is used to test the pattern before sampling begins
Getting the pattern right before sampling saves significant time and cost. At OFC, our team handles pattern making in-house, so nothing gets lost in translation.
Step 5: Sampling
Sampling is where your design comes to life for the first time, and it's one of the most exciting (and sometimes humbling) parts of the process.
A sample is a physical prototype of your garment, sewn using your chosen fabrics and materials according to your tech pack and patterns.
Types of samples you may encounter:
Proto Sample: first rough version to test construction and fit
Fit Sample: refined version to confirm sizing and proportions
Sales Sample: final version used for lookbooks and buyer presentations
Pre-Production Sample (PPS): approved final sample that locks in all production details
Never skip sampling. It is the single most important step to ensuring your finished product matches your vision. Brands that rush straight to bulk production almost always pay for it with expensive mistakes.
At OFC, we manage the entire sampling process, from coordinating with factories to reviewing and revising until the sample is exactly right.
Step 6: Production
Once your pre-production sample is approved, you're ready for bulk production. This is where your garments are manufactured at scale.
What the production phase involves:
Fabric and trim procurement in bulk quantities
Cutting: fabric is cut according to patterns in layered stacks for efficiency
Sewing: garment pieces are assembled by skilled operators
Finishing: buttons, zippers, trims, and labels are applied
Quality control (QC): each garment is inspected against your approved PPS
Packing and shipping prep
Production timelines vary depending on the complexity of the garment, order quantity, and factory capacity. At OFC, we work with vetted manufacturing partners right here in Los Angeles, which means faster turnaround, better communication, and quality you can trust.
Step 7: Quality Control & Delivery
Quality control is not just a final inspection. It's built into every step of the production process at OFC. Before any order ships, our team conducts thorough QC checks against your approved sample.
OFC's QC process includes:
Measurement checks against your tech pack specifications
Construction and stitching inspection
Fabric and colorway verification
Label and packaging compliance
Once QC is passed, your order is packed and shipped, either directly to your warehouse, fulfillment center, or retail partners.
Why Work With Outsourced Fashion Consulting?
The apparel production process has a lot of moving parts. Most emerging brands try to manage them independently, piecing together freelance designers, overseas factories, and sourcing agents, and end up losing time, money, and control of their product.
OFC exists to change that.
As a full package manufacturer based in Los Angeles, we handle every step of the process under one roof:
Product development and design
Fabric and material sourcing
Tech pack creation
Pattern making and grading
Sampling and revisions
Full production runs, from 200 units to 10,000+
Quality control
We've helped brands across menswear, womenswear, denim, activewear, swimwear, streetwear, and kids' apparel bring their vision to life the right way.
