Isabelle Harrison has officially partnered with beauty brand ONE/SIZE, founded by makeup artist Patrick Starrr for a new campaign that puts her game-day beauty routine in the spotlight.
In the spot, the WNBA veteran walks viewers through her pre-game and practice looks before heading into a full workout, wrapping up with a towel test to show the products stayed locked in through real sweat.
The partnership marks Harrison’s first collaboration with ONE/SIZE, coming on on the heels of her signing with FirstPick Management. Toronto Tempo, Canada’s first-ever WNBA franchise, signed Harrison ahead of their inaugural 2026 season. Off the court, she has been active with Spectrum and Jordan Brand deals.
For ONE/SIZE, the campaign continues a deliberate push into basketball. DiJonai Carrington had previously partnered with the brand, helping build its credibility within on-court beauty culture.
Harrison and DiJonai Carrington are not the only WNBA stars securing brand partnership deals. Caitlin Clark’s recent Xfinity campaign reflects the broader wave of WNBA stars driving major brand investment.
ONE/SIZE’s On Til Dawn Setting Spray became Sephora’s number one makeup item overall in 2025, giving the brand real commercial momentum to build on with athlete-driven storytelling.
Takeaways
ONE/SIZE isn’t just riding the WNBA wave, it’s building a lane within it. By going from Carrington to Harrison, the brand is quietly assembling a basketball-adjacent roster that feels authentic rather than opportunistic.
For Harrison, this is smart portfolio-building: she’s entering a historic first season in Toronto with three visible off-court partners already in place (Spectrum, Jordan Brand, and now ONE/SIZE), which signals serious commercial momentum for a player entering her 10th WNBA season.
The towel test angle is particularly savvy storytelling. It’s not just a campaign, it’s a product demo tied directly to athletic performance, which is exactly the kind of content that travels well on social media and resonates with WNBA fans who already follow these athletes for beauty and style content.
Can ONE/SIZE become the go-to beauty brand of the WNBA the way other brands have owned specific culture lanes in men’s basketball? Will other beauty brands accelerate their pursuit of WNBA athletes now that ONE/SIZE has demonstrated the formula with Carrington and Harrison?
