When it comes to building a brand that stands out, your denim line can be the defining product. But how exactly is a pair of jeans made—from raw materials to that perfect wash and fit? Many brands struggle with inconsistent quality, long lead times, and unclear production steps. That’s why understanding the full manufacturing process of jeans is crucial. At EVELYN FASHION, we’ve helped dozens of brands bring their dream denim to life. Here’s how we do it.
To craft a perfect pair of jeans, we follow a comprehensive process that includes sourcing the right denim fabric, designing with purpose, manufacturing with precision, and running multiple quality inspections. From concept to shipping, we manage each step in-house or with our certified partner factories.
Still curious about what goes into every stitch of a pair of jeans? Let me take you behind the scenes of our process.
What materials are used to make jeans?
The first step in making jeans is choosing the right fabric. We typically use high-quality cotton denim with varying percentages of elastane or polyester, depending on the fit and stretch requirements.
At Evelyn, we work with a network of reliable fabric mills across China to source certified, durable denim that matches your brand’s aesthetic. Want to use organic cotton or recycled fibers? We’ve got that covered too.
How do we design a pair of jeans?
Once we lock in the fabric, we move to the design stage. Our in-house designers collaborate closely with your team to sketch and tech-pack your jeans. Whether it’s high-waisted skinny jeans, straight-leg classics, or trendy wide-leg cuts, we help bring your vision to life.
We also take care of key details like pocket shapes, stitching lines, zipper and button placements, and wash effects. Want a vintage acid wash or raw indigo look? We’ll mock up the samples for you.
How are jeans cut and sewn?
With approved designs, we move to sample-making. First, we cut the fabric using CAD-guided machines to ensure precision and minimal waste. Each panel—front leg, back leg, pockets, waistband—is labeled and batched.
Then, our team assembles the jeans in a set sewing process. This includes stitching panels, adding rivets, attaching belt loops, and reinforcing key stress points. Depending on the complexity, sewing one pair of jeans can involve 12–20 steps.
What kind of washes and treatments are applied?
This is where the magic happens. Raw jeans are washed, distressed, or dyed using various finishing techniques. Some popular options include:
-
Stone washing
-
Enzyme washing
-
Bleaching
-
Laser fading
-
Hand scraping
Each wash affects the final color, softness, and vintage look of the jeans. We test different treatments in small batches before full production.
How do we ensure the quality of each pair?
At Evelyn, quality control is a continuous process. We inspect raw materials, monitor stitching during production, and perform final checks on fit, appearance, and durability.
We follow AQL standards for random sampling and visual inspections. Every batch is reviewed by our trained QC team before it’s packed and shipped. And we do metal needle test to confirm every piece is safety free.
What packaging is used for jeans?
Once approved, jeans are folded, tagged, and packed in eco-friendly polybags or custom packaging, depending on your branding needs. Bulk orders are organized by SKU and size before shipping.
We also help with hangtags, woven labels, size stickers, and barcodes—all the finishing touches that give your jeans a retail-ready look.
Can jeans be made sustainably?
Yes! More brands today request sustainable denim. We support this by offering:
-
Organic or recycled cotton denim
-
Low-water and non-toxic dyeing processes
-
Laser finishing instead of harsh chemicals
-
Recyclable or biodegradable packaging
We also work with certified factories that meet BSCI, SEDEX, or GOTS standards.
How long does it take to manufacture jeans?
A typical jeans production order at Evelyn takes:
-
10–15 days for fabric and trims sourcing
-
7–10 days for sampling
-
25–40 days for bulk manufacturing
-
7 days for final inspection and shipping prep
Timelines vary by order size and customization level, but we always provide a clear schedule upfront.
What challenges should brands prepare for?
If you’re new to denim, expect challenges like:
-
Fabric shrinkage after washing
-
Color variance between batches
-
Fit issues due to body grading
Our team helps you solve these with pre-testing, wash trials, and clear communication throughout the process.
Can you start small?
Absolutely. We support MOQ as low as 300 pieces per style per color, especially for new or emerging brands. As your business grows, we’re ready to scale with you—while keeping quality consistent.
