DENIM TRENDS: WHAT CONSUMER RESEARCH REVEALS

 

Denim trends come and go, but consumers always expect comfort and performance. And when it comes to jeans, spandex and elastane fiber technology makes all the difference. 

In recent years, away-from-the-body silhouettes have gained popularity among younger consumers. But while the era of skin-tight, ultra-stretch skinny jeans may be in the past, rigid, 100% cotton jeans can feel restrictive and often lose their shape over time because they lack recovery power — and that’s just not good enough for on-the-go consumers. 

The demand for stretch denim fabrics — especially from the waist to the knees — has only intensified. According to a report from Cognitive Market Research, consumers are willing to pay for comfortable stretch fabrics, premium quality, and innovative fits.

Our 2025 consumer research* confirmed the same: Of the more than 2,500 participants we surveyed — from ages 18 to 59 and in six countries — 69% said that being able to "move freely and easily" was a top criterion for choosing ready-to-wear clothes.

With LYCRA® brand fibers, denim manufacturers can deliver the comfort and performance today's consumers demand while maintaining the authentic denim aesthetics they love. Because regardless of silhouette, great denim should feel as good at the end of the day as it did at the start.

LYCRA® VINTAGEFX FIBER

LYCRA® VINTAGEFX FIBER

LYCRA® VintageFX fiber is a powerful dual-core yarn, engineered to produce long-wearing, comfort-stretch denim that looks and feels like a favorite pair of vintage jeans — so consumers can enjoy looser-fitting jeans that retain the comfort of LYCRA® fiber. 

LYCRA® VintageFX denim fabrics are less bulky than traditional denim and offer a soft drape, empowering designers to innovate new silhouettes that deliver the perfect balance of form, function, and heritage aesthetics.

Crafted from 70% industrial or dent corn grown in the US Midwest, this fiber has the potential to reduce the carbon footprint of LYCRA® fiber by up to 45%*. It delivers the same performance as our classic LYCRA® fiber — with a lighter touch on the planet. So brands and mills can drop it into their denim lines with ease and get closer to their sustainability goals.

LYCRA® ADAPTIV FIBER

LYCRA® ADAPTIV fiber’s unique chemistry adapts to the wearer’s needs. In motion, it delivers a second-skin fit that doesn’t shift around, boosting the wearer’s comfort and confidence. At rest, it adjusts its compressive force to deliver just-right fit, shape, and control. Plus, its softer stretch means jeans are easier to put on and take off, and sizing is more inclusive for all body types.
