Toronto-based Knix, known as North America’s top Leakproof undergarment brand, has officially launched in six Holt Renfrew locations across Canada. The partnership includes two dedicated pop-ups, offering a curated selection of the brand’s best-selling products. For Knix, this collaboration with Holt Renfrew marks a significant milestone in its retail journey as it scales beyond its direct-to-consumer roots into premium wholesale distribution.
“This partnership with an iconic Canadian retailer who we’ve long admired is an incredible opportunity for Knix to expand its customer base,” said Joanna Griffiths, Founder and President of Knix. “Offering our customers another in-person touchpoint is something we’re continuously exploring, and we can’t wait for everyone to shop the curated assortment at the Holt Renfrew location closest to them.”
Elevated Experience for a New Audience
Holt Renfrew’s reputation as Canada’s leading luxury retailer made it a natural partner for Knix, which has built a loyal following through innovation, inclusivity, and high-performing product design.
“We are proud to curate the best fashion and lifestyle edits from Canada and around the world,” said Carolyn Wright, Senior Vice President, Product, at Holt Renfrew. “Introducing this innovative, female-led Canadian brand to our customers is a wonderful new addition to our assortment in stores and online this spring.”
The in-store experience, which runs until May 26 for the pop-up locations, is designed to showcase Knix’s most sought-after pieces including the brand’s famous Leakproof underwear, the Revolution Bra, Gossamer Lace sets, and a growing range of swimwear.
Retail Locations Across Canada
Knix is now available at Holt Renfrew locations in Toronto (Bloor Street and Yorkdale), Vancouver, Mississauga (Square One), Calgary, and Montreal (Holt Renfrew Ogilvy). The Bloor Street and Vancouver stores feature pop-up spaces, while the remaining four locations have integrated the brand into their core assortment.
The pop-ups serve as a tactile introduction to the Knix brand for Holt’s clientele. “We really wanted to showcase who we are through these touchpoints,” said Nicole Tapscott, Chief Commercial Officer at Knix. “From our newest swim drops to our best-selling shapewear, we’ve curated a premium assortment that reflects our design innovation and commitment to inclusivity.”
The pop-up experience, she added, has also allowed Knix to showcase mannequins in a range of body types. “It’s important for customers to see themselves reflected—not just in the marketing, but in the physical store environment too.”
From Leakproof to Luxe
Tapscott explained that the Holt Renfrew team was particularly drawn to Knix’s rapidly growing swimwear category. “Swim is one of our fastest-growing areas,” she said. “We’re excited to highlight new silhouettes and seasonal colours—espresso is one of our key colours this year—as well as our signature Leakproof technology that makes Knix unlike anything else in the market.”
Among the featured swimwear are bold prints and refined cuts, such as the Sculpt Ruched One-Piece, as well as new lifestyle offerings including oversized linen shirts and organic cotton cover-ups.
While not all items include the brand’s signature Leakproof technology, the assortment still emphasizes performance and style. “We’ve got our Gossamer Lace and Mesh Lace underwear in both light and full absorbency,” added Tapscott. “These started as limited holiday collections but did so well we brought them back in multiple colours.”
Breakthrough in Customizable Shapewear
Another standout in the assortment is Knix’s customizable shapewear—a world-first product designed with versatility in mind. Tapscott highlighted how the shapewear can be cut along three built-in seams to adjust the depth for different outfits.
“This is really popular among stylists,” she said. “They don’t want to carry ten shapewear options to a fitting—just one of these works for multiple looks. Customers can cut it themselves based on their needs, and it’s all part of our Leakproof line.”
A short version of the customizable shapewear is also featured, addressing common issues like dressing around slits while maintaining support and comfort. “Retail is so much more personalized now. People are mixing and matching across decades and aesthetics,” Tapscott noted. “This shapewear helps unlock your whole closet.”
Shared Values and Strategic Growth
When asked why Holt Renfrew was the right partner, Tapscott was clear: “From the way they approach fashion to the way they operate as an institution in Canada—and globally—Holt Renfrew was top of our list,” she said.
“There’s a strong customer overlap. They were excited about the demographic we bring in and about introducing fashion-forward functionality to their shopper.”
Knix’s entrance into Holt Renfrew also serves as a brand awareness play, particularly in cities where the brand has no standalone stores. “We’re giving customers another channel to touch and feel the product,” Tapscott explained. “Many need to see it to believe it.”
What’s Next for Knix Retail
Knix currently operates 13 standalone stores, with six more planned for this year. Much of the upcoming growth will focus on the U.S. market. “We’re investing heavily in retail expansion, especially south of the border,” said Tapscott. “But Canada remains core to our identity.”
Tapscott believes the brand’s success is driven by both community and product. “Once someone tries our product, they’re hooked,” she said. “Customer retention is incredibly strong. But it all starts with that first try. That’s why partnerships like this one with Holt are so important.”
