What Is Denim Fabric Made Of? Understanding the Material Behind Tailored Jeans

What Is Denim? A Brief Introduction

Denim is a strong, durable fabric most commonly made from 100% cotton, woven in a twill weave pattern. Its hallmark is the diagonal ribbing visible on one side of the fabric. Denim originated in France in the 17th century, known as “serge de Nîmes,” later shortened to denim.

Over time, denim evolved into the global standard for hardwearing, stylish bottoms — most notably jeans.

Key Components of Denim Fabric

Cotton – The Base of Most Denim

Most denim fabrics start with cotton — a breathable, biodegradable natural fiber. High-quality denim, like those used in tailored jeans, is typically crafted from long-staple cotton, which offers:

• Greater strength
• Less pilling
• Improved softness with wear

You may also come across organic cotton or recycled cotton, part of a growing trend in sustainable fashion.

Indigo Dye – The Iconic Colouring

Traditional denim is dyed using indigo, a deep blue pigment derived either from the Indigofera plant or synthetic sources. The yarns are dyed only on the surface, which allows the fabric to age beautifully, fading over time to produce a natural patina unique to every wearer.

Weave Structure – Twill Weave

Denim’s twill weave means that:

• The weft yarn passes under two or more warp yarns
• The diagonal pattern appears on the face of the fabric
• It creates a stronger, more resilient fabric than plain weaves

Types of Denim Used in Tailored Jeans

Selvedge Denim

Selvedge (or selvage) denim is woven on old-style shuttle looms, producing a self-finished edge that prevents fraying. It’s known for its:

• Tighter weave
• Longevity
• Clean finished seams

At Tailored Jeans, we source selvedge denim from mills in Japan, Turkey, and Italy — each known for exceptional weaving techniques.

Stretch Denim

Adding a small amount (1–5%) of elastane (spandex) to cotton creates stretch denim. This type offers:

• Flexibility
• Improved comfort
• Better fit retention

Ideal for custom jeans where precision fitting matters.

Raw vs. Washed Denim

• Raw denim: Unwashed, untreated — fades naturally with wear
• Washed denim: Pre-treated to reduce shrinkage and create different looks like stone-wash or acid-wash

Custom jeans can be tailored from either, depending on personal preference.

Innovations in Sustainable Denim

Modern denim manufacturing has begun incorporating:

• Recycled fibers: Such as post-consumer denim waste
• Low-impact dyes: That reduce water usage
• Eco-friendly finishing: Like ozone washing or laser fading

Tailored Jeans is committed to offering sustainable options for customers who care about their environmental footprint without sacrificing quality.

Why Material Matters in Custom Jeans

When you’re choosing tailored jeans, the type of denim used impacts everything — from the fit and comfort to how the jeans age over time. Here’s why:

• Thicker denim (12oz–16oz) is ideal for structured fits
• Lighter denim (8oz–11oz) works for summer or relaxed styles
• Selvedge ensures cleaner inside seams
• Stretch blends suit slim and skinny fits

By selecting the right denim for your body, lifestyle, and climate, you’re investing in jeans that perform better and last longer.

Denim is more than just fabric — it’s a blend of history, innovation, and craftsmanship. At Tailored Jeans, we take denim seriously. That’s why we offer a wide variety of denim types, from classic indigo selvedge to lightweight summer blends, all customizable to fit your needs.
