Quality Control in Garment Manufacturing: How It Works

Quality control is an often overlooked (and non-glamourous) part of garment manufacturing. 

The truth is – there’s a lot of technical work that goes into making garments, from the initial design concept to the final delivery.

And quality control is a huge part of that, ensuring every seam, stitch, and fit meets the required standards.

If you’re curious about how quality control in garment manufacturing works, then you’re in the right place. 

In this article, I’ll delve into the importance of quality control in garment manufacturing, explore different methods of conducting quality checks, address challenges, and guide you on navigating this process. Because whether you’re an in-house designer, freelance fashion designer, or starting your own brand, you need to understand the quality control process.

Why am I qualified to write about this stuff? In my 15 years of experience in the fashion industry, I’ve journeyed from being an in-house designer, starting my own brand (yep!), to growing my freelance career to $100,000+. Now, with all the knowledge I’ve learned along the way, I want to help fashion designers (and PDs, TDs, etc.) like you make it in the industry.

What is Quality Control in Garment Manufacturing?

Quality control in garment manufacturing is a set of systematic procedures that ensures a product meets required standards. 

It involves processes from inspecting the materials, checking for fabric defects, ensuring production methods, and reviewing the finished goods to identify and address any inconsistencies from the desired specifications. 

If you’re sick of dealing with negative feedback on your product review page, quality control is not something you want to take lightly. And at its worst, product returns and recalls due to quality control failure are not only a big expense to fashion brands, but also impact the brand’s name negatively.

An efficient garment quality control helps nip these issues right in the bud.

Types of Quality Control Methods

There are several ways to ensure quality during garment manufacturing. These can be sorted into the different stages of production – during pre-production, while in production, and upon finishing production. 

While each method of quality control inspection has a different goal, having these checkpoints throughout the entirety of the garment manufacturing process ensures potential issues are taken care of early, avoiding further complications down the line.

Pre-production Quality Control

This phase involves a series of steps to ensure that all necessary quality requirements are met before actual production begins. Thorough inspection and assessment are done on the materials, equipment, and samples before they get approved for manufacturing. 

Examples of Pre-production Quality Control Methods include:

  • Materials Inspection: Thoroughly examining fabric, trims, and components before production to identify any fabric defects or discrepancies.
  • Fabric Shrinkage and Color Fastness Tests: Fabric quality control tests like these anticipate potential issues like shrinkage, bleeding, fading, and other fabric defects. These tests ensure that garments maintain their intended dimensions and colors even after washing and prolonged use.
  • Sample Testing: Creating and inspecting prototype garments to confirm they match design and quality expectations.

In-line Quality Control

In-line Quality Control takes place during the manufacturing process itself. For example, in-line quality control can be done during fabric cutting, sewing and assembly, finishing, and so on. This method ensures that potential defects are identified and fixed in real-time, minimizing the likelihood of large-scale quality issues later on.

Examples of In-line Quality Control Methods include:

  • Random Inspections: Periodic checks during production to ensure random samples meet quality standards. 
  • Dimensional Checks: Verifying garment measurements and dimensions to ensure they follow the specifications in your tech pack. 
  • Stitching Inspection: Monitoring the sewing process to catch any stitching defects or irregularities.

Post Production Quality Inspection

Post Production Quality Inspection is the final step of quality checking done before garments are packaged for delivery. This phase involves a comprehensive inspection to verify that the finished products meet the desired quality standards and get green light for distribution.

Examples of Post Production Quality Control Methods include:

  • Final Random Inspection: Randomly selecting finished goods for a comprehensive quality check before shipment. Inspectors make sure everything from labeling to packaging requirements meets an acceptable quality level.
  • Functionality Testing: Ensuring that zippers, buttons, and other features work as intended. 
  • Appearance Assessment: Evaluating overall appearance, including color, print alignment, and overall aesthetics.

Who Should be in Charge of Quality Control Inspections?

Honestly, I’ve gone through loootsss of quality control issues that I almost wanted to do the inspection myself.

Kidding aside, there are people in charge of doing this work. And especially for remote freelance fashion designers working for brands around the world – knowing who’s responsible for these tasks is important.

Let’s explore some potential candidates.

who is in charge of quality control inspections

The Manufacturer

Oftentimes, manufacturers have their own team of quality inspectors in their factories. They can be tasked to check every step of the production process – from fabric spreading, garment assembly, up until final inspection. However, while it’s highly convenient to have QC inspectors from the manufacturer, a lot of fashion brands worry about bias and inconsistencies when it comes to using the factory’s own inspectors.

True Story: I once evaluated a poorly fitting garment with “perfect” dimensions as per the manufacturer’s measurements. My instinct prompted me to cross-check these measurements, and to my surprise, they were way off tolerance. And I’m not saying all manufacturers are like this, but it’s really important to be proactive when it comes to quality checking.

Third Party Inspectors

Hiring a third-party inspector can provide a more unbiased view towards garment quality checking. While it is possible to hire individuals or teams and train them up to do quality control inspection, there are also existing organizations that offer these services and may follow international standards set by organizations such as the ISO (International Organization for Standardization).

In-House Quality Inspectors

Larger brands may employ in-house inspectors who oversee the entire manufacturing process right from selecting raw materials to approving the finished products. This hands-on approach involves continuous monitoring and a well-established feedback system, enhancing overall product quality through on-going refinements.

Pro Tip: Big fashion brands may deploy not only one but two or all of the quality control methods mentioned above. Deciding which one to use for your fashion brand ultimately depends on your own circumstances including your size, budget, proximity, and overall goal for the brand.

Benefits of Good Quality Control in Garment Manufacturing

Implementing best practices for quality control can offer you reassurance and confidence (and help you sleep peacefully at night!) – knowing that your products meet the quality standards and are made to last.

Here are the reasons why you should do it now rather than later. 

  • Increased Customer Satisfaction: In the fashion industry, a happy client = happy life. Consistent quality leads to satisfied customers who are more likely to return and recommend your brand to others. 
  • Good Brand Reputation: Reliable quality control enhances a brand’s reputation for producing high quality garments. If you want your reviews to be flooded with positive reviews, QC is a must!
  • Minimized Defects and Returns: Strict quality control measures reduce the likelihood of defects reaching customers. I’m sure you’ve been on the receiving end before, and it’s no fun!
  • Efficiency and Cost Savings: The truth is – quality defects are not only headaches for product development but also contribute to so much material and $$$ wasted. Detecting and addressing issues early in the production process avoids costly rework and additional waste. 
  • Process Optimization: Continuous quality monitoring prompts manufacturers to identify bottlenecks and areas for improvement in the production process, leading to higher efficiency and output.

Best Practices for Quality Control in Garment Manufacturing

Here are some tips to keep your quality control processes in check.

  • Establish clear quality standards: Establish detailed quality standards for your garments, materials, and processes. This is where your standard documents in the apparel industry like your How to Measure Guide, tolerances, and other QC related regulations come into play.
  • Provide comprehensive training: Hiring QC staff is one thing, but training them based on your own expectations is another. Train your staff, including quality control inspectors and production workers on quality standards, defect identification, and best practices to maintain consistency.
  • Collaborate with suppliers: Do not underestimate the power of working closely with your manufacturers and suppliers. Foster open communication between quality control teams and production staff to address issues promptly. Collaborate with suppliers to address any recurring quality issues and work together to implement effective solutions. 
  • Document processes and findings: Make sure to maintain clear records of quality control processes, inspections, and identified defects. This documentation will help in tracking trends and making informed decisions down the line.
  • Ensure regulatory compliance: Stay updated with relevant apparel industry regulations and standards to ensure that products adhere to safety and quality requirements. 
  • Seek feedback: Gather feedback from customers and retailers to identify any quality concerns and make necessary improvements. 
  • Encourage continuous improvement: Regularly review quality control processes to identify areas you can improve. Encourage feedback from production teams to implement refinements. 

Quality control in garment manufacturing isn’t just a single step; it’s a series of processes that lay a solid foundation for manufacturing and growth. While these processes may take time and effort, they save you from much more trouble in the long run. 

Your dedication to this process shapes not only your garments but also your brand’s reputation in this highly competitive industry.

Get the Freedom and Pride That Comes with Taking Charge of Your Own Destiny in Fashion

I’m Heidi, and I believe that you can do things differently in your fashion career.

Because the truth is, most industry jobs will underpay and overwork you. Having your own brand is far from profitable (and let’s be honest, most of them fail). 

So if you ACTUALLY want to work as a fashion designer and get paid, the best way to do it is as a freelancer.

Now, maybe you’ve been told that “brands don’t accept remote freelancers”…

Or believe that freelancing means being an exploited temp employee working full time without benefits…

Or to freelance, you have to be a rockstar expert with allll the skills from design through development

I’m going to show that it IS possible to be a REAL freelancer in fashion, work remotely with brands you love, AND make money (even if you’re terrified you don’t have all the answers).
