Fabletics is making a strategic move beyond its athleticwear roots with the launch of its first-ever denim collection, signaling how deeply the “casualization” trend is reshaping the modern apparel market.
For the company—founded in 2013 as a digital-first challenger to brands like Lululemon—the expansion into denim represents more than a new product category. It reflects a broader shift across fashion retail: consumers increasingly expect performance brands to deliver clothing that works both in workouts and everyday life.
As CEO Adam Goldenberg recently noted, shoppers now want the same comfort and flexibility from their daily wardrobes that they once only expected from gym apparel.
Why Denim Is the Next Step for an Activewear Brand
The new denim collection will be available online and in select Fabletics stores, marking the retailer’s latest step in expanding its product ecosystem.
To ensure credibility in a category traditionally dominated by heritage brands, Fabletics partnered with denim specialist Benjamin Talley Smith to design the line. The collection emphasizes three elements long associated with the brand’s identity: comfort, fit, and modern style.
The launch includes:
•11 different denim styles
•three levels of stretch
•seven wash variations
•three inseam lengths
The products cover both women’s and men’s collections.
Women’s pieces include high-rise wide-leg, straight, and skinny jeans, alongside a mid-rise baggy style, a denim mini skirt, and a denim jacket. Men’s options feature slim, straight, and baggy fits, along with baggy utility jeans and a classic trucker jacket.
The goal is to bring athleticwear-level comfort into a traditionally rigid category.
Talley Smith said the design process focused heavily on achieving consistent fit across a wide range of body types. Instead of simply resizing one base pattern, the brand individually adjusted each size to ensure better fit across the collection.
The Casualization of Fashion Is Accelerating
Fabletics’ denim launch is part of a much larger industry shift.
Over the past decade, athleisure has blurred the line between performance apparel and everyday fashion. Consumers now routinely wear workout-inspired clothing to offices, travel, and social events.
Goldenberg says that trend continues to accelerate.
Shoppers are already wearing Fabletics products far beyond the gym. The company’s men’s Don Pant, for example, has become a versatile wardrobe item used for everything from conferences to golf outings.
That behavior mirrors the success of Lululemon’s ABC Pant, a product widely credited with helping normalize athletic-inspired workwear.
As Goldenberg puts it, the entire industry is moving toward comfort-first clothing, creating new opportunities for brands to extend their reach into adjacent categories.
Fabletics Isn’t Alone in Crossing Into Denim
The move also reflects a broader strategic pattern among emerging athletic brands.
Competitors are testing similar category expansions:
•Vuori, a fast-growing athleisure brand, has introduced its own denim offerings.
•Outdoor Voices, after its recent brand reset, has experimented with denim products as well.
These moves suggest that denim—once dominated by legacy labels—is now becoming another battlefield in the rapidly evolving comfort-driven apparel economy.
For performance brands, the opportunity is clear: apply technical fabrics, stretch, and ergonomic fit to everyday staples.
Membership Economics Power the Strategy
Fabletics’ expansion strategy is also tightly linked to its membership-driven business model, which remains one of the company’s core competitive advantages.
Under its VIP program, shoppers receive discounted pricing in exchange for a monthly membership that can be paused or skipped at no cost.
Pricing for the new denim line reflects this model:
•Standard shoppers: $109.95 to $174.95
•VIP members: $79.95 to $119.95
According to Goldenberg, the program plays a central role in the brand’s financial performance.
Approximately 80% of customers who shopped in the past year are members, and those members generate about 95% of the company’s revenue.
The model creates predictable revenue while encouraging customers to remain within the brand’s ecosystem.
Expansion Strategy Is Boosting Customer Spending
Early signs suggest the strategy is working.
As Fabletics has expanded its product assortment—from activewear into categories like scrubs and now denim—customers are spending more within the brand.
Goldenberg says Fabletics’ share of customers’ apparel spending has grown significantly, with wallet share increasing from 22% to 30%.
That metric suggests the brand is successfully evolving from a niche fitness label into a broader lifestyle apparel platform.
A Careful Expansion, Not a Category Free-for-All
Despite the expansion, Fabletics leadership says it is deliberately selective about entering new categories.
Goldenberg outlines three criteria before launching a new product line:
•The category must align with the brand’s performance-focused DNA.
•Customers must actively want the product from Fabletics.
•The company must believe it can execute better than competitors.
In other words, expansion isn’t about chasing trends—it’s about extending the brand’s strengths into adjacent markets.
The Bigger Picture: Performance Brands Are Becoming Lifestyle Brands
From an industry perspective, Fabletics’ denim launch highlights a major transformation underway in apparel retail.
The traditional boundaries between sportswear, casualwear, and lifestyle fashion are rapidly disappearing.
Consumers increasingly prioritize three things:
•comfort
•versatility
•value
Brands that can combine those attributes across multiple categories stand to capture a larger share of customers’ wardrobes.
Fabletics appears to be betting that the future of apparel belongs not to single-category brands—but to multi-purpose lifestyle platforms built around comfort-first design.
If that bet proves correct, denim may only be the beginning.
