Great garments don't happen at the cutting table. They happen long before that — in the development process, where decisions about fit, fabric, and construction get made, tested, and refined before a single production unit is cut.
For brands new to apparel manufacturing, this phase can feel opaque. What's actually involved? How long does it take? Why do samples go through so many rounds? Here's a clear breakdown of how premium knit apparel gets built — and why each step matters.
It All Starts With the Pattern
A pattern is the blueprint of a garment. It determines fit, silhouette, seam placement, and construction details. For knit basics specifically — t-shirts, hoodies, fleece, tanks — patternmaking is more technical than it looks, because knit fabrics behave very differently from woven ones.
A knit patternmaker has to account for stretch percentage, fabric recovery, shrinkage, and wash behavior — all of which change how a garment fits after it leaves the production floor. A pattern engineered for a raw sewn measurement will fit completely differently after a garment wash or dye process. Getting those calculations right upfront is what separates garments that fit consistently from ones that are a gamble.
At US Standard Apparel, patternmaking happens in conjunction with our in-house fabric production. Because we develop our own fabrics, our patternmakers already know how each material behaves — they're not guessing on shrinkage rates or stretch percentages. That context produces better patterns, faster.
From Concept to Tech Pack
Before a pattern gets made, the garment needs a clear spec. That spec lives in a tech pack — the document that defines everything about the garment: measurements, construction details, stitch types, trim specifications, label placement, fabric information, and artwork placement if applicable.
A well-made tech pack is the single most important communication tool between a brand and its manufacturer. Vague direction at the spec stage gets amplified into production problems later. Brands that invest in clear, detailed tech packs move through development faster and with fewer costly surprises.
If you're working with us on a private label program, our team can help you build out specs based on your fit direction and design intent.
Sample Making: Why It Takes Multiple Rounds
Once the pattern and spec are set, the sample room produces the first physical prototype. This is where the garment goes from blueprint to reality — and where reality often diverges from the plan in ways you need to catch before bulk production.
The first sample (called a proto) is almost never the final version. Typical issues at the proto stage include neckline tension, sleeve proportions, body length, and how the fabric behaves at seams and hems. These get identified, documented, and corrected before moving to the next round.
Most development programs go through two to four sample rounds before a fit is approved. That process is not inefficiency — it's how quality garments get built. Trying to skip or rush sample rounds to save time almost always costs more in production corrections later.
Wash Testing and Garment Dye Testing
For knit basics going through garment dyeing or wash finishing, a critical development step happens after sewing and before bulk production: wash testing.
Garment dyeing and washing change a garment — sometimes dramatically. Fabrics shrink, colors shift, hand feel changes, seams can pucker or twist. Wash testing establishes how the garment performs through the finishing process and what the final measurements look like post-wash. Premium basics brands often build their official size specs around post-wash dimensions rather than raw sewn measurements, because that's what the customer actually receives.
US Standard Apparel's Americana Jersey — our 18/1 U.S. cotton fabric — is designed specifically for garment dyeing. The fabric is developed to accept dye evenly and age beautifully with wear, which requires specific construction decisions built into the pattern and sample process from the start.
Grading Into a Full Size Run
Once the base size is approved, the garment gets graded — expanded into a full size range (XS through XXL, or whatever range the brand needs). Good grading maintains proportional fit across sizes, not just scaled-up measurements. A graded XL should fit an XL customer the way the sample fit the fit model — with the same proportions, balance, and drape.
This step gets skipped or done cheaply by some manufacturers, and it shows in the product. Brands with grading problems end up with a great-fitting medium and a strange-fitting large. Building this step carefully pays off in customer satisfaction and reduced returns.
Why Los Angeles Is the Right Place to Develop Knit Basics
The LA manufacturing ecosystem has a density of specialized vendors — patternmakers, sample rooms, knit mills, garment dye houses — that doesn't exist in many other places. That proximity matters enormously for development speed.
When a brand needs a fit revision, a same-city turnaround takes days. Overseas development cycles take weeks per round. For a program going through four rounds of samples, that difference compounds quickly. Brands that develop in LA can move from concept to production-ready garment significantly faster.
US Standard Apparel operates in Vernon, CA — at the center of this ecosystem — with in-house fabric production, pattern development, sample making, and full garment manufacturing all under one roof.
The Bottom Line on Development
Development is an investment, not a cost to minimize. The brands that consistently produce great product are the ones that take development seriously — committing to multiple sample rounds, testing wash processes before bulk, and building patterns that account for how their specific fabrics behave.

Frequently Asked Questions
What is patternmaking in clothing manufacturing? Patternmaking is the process of creating the technical blueprint for a garment — defining fit, silhouette, seam placement, and construction details. For knit fabrics, patternmaking must account for stretch, recovery, and shrinkage behavior, which affects how the final garment fits after washing and dyeing.
How many sample rounds does it take to produce a garment? Most premium knit programs go through two to four sample rounds before a fit is approved for bulk production. Each round addresses fit issues identified in the previous sample. Trying to rush this process typically results in more expensive corrections during production.
What is a tech pack in apparel manufacturing? A tech pack (technical package) is a document that specifies everything about a garment: measurements, construction details, stitch types, trim specs, label placement, fabric information, and artwork placement. It's the primary communication tool between a brand and manufacturer.
Why is wash testing important in garment development? Garment dyeing and wash finishing change a garment's dimensions, hand feel, and appearance. Wash testing before bulk production establishes the final post-wash measurements and identifies any construction issues — seam puckering, twisting, shade variation — before they appear at scale.
What does grading mean in apparel? Grading is the process of scaling a garment pattern from a base size into a full size range. Good grading maintains proportional fit across sizes — not just larger or smaller measurements, but the correct proportional relationships that make each size fit its target customer well.
