Hailey Bieber Rewrites the Lingerie Playbook at Saint Laurent’s Spring 2026 Show

Inside Hailey Bieber’s Saint Laurent Moment: When Athletic Meets Intimate in Perfect Harmony

There are fashion moments, and then there are statements. On Monday, perched in her customary throne at the Saint Laurent Spring 2026 ready-to-wear presentation during Paris Fashion Week, Hailey Bieber delivered the latter with the kind of insouciant confidence that has become her sartorial signature. The Rhode Beauty founder—equal parts California cool and continental chic—transformed intimate apparel into a masterclass on modern dressing, proving once again why she remains fashion’s most compelling style chameleon.

The pièce de résistance? A pair of butter-yellow satin underwear, delicately trimmed with cream floral lace, worn unabashetically as short-shorts. This wasn’t merely pajamas-as-daywear; this was lingerie liberated, a brazen reinterpretation of boundaries that fashion has been flirting with for seasons. Layered over sheer black tights, the exposed undergarment created a study in contrasts—demure yet daring, vintage yet utterly contemporary. The lemontini hue, just a whisper brighter than this season’s omnipresent butter yellow, featured a curved hemline and ruffled lace trim that elongated her frame while nodding to boudoir sensibilities of decades past.

But Bieber, ever the stylist’s dream, refused to let the look veer into costume territory. Enter: a two-tone tracksuit jacket in complementary orange shades, cropped at the bubble hem with a relaxed, quarter-zip silhouette that injected athletic pragmatism into the romanticism below. It was high-low dressing executed with surgical precision—the kind of ensemble that could theoretically accompany a morning coffee run, yet felt entirely appropriate for fashion’s most prestigious front row.

Her accessories told their own story. Strappy orange heels in a glossy, almost lacquered finish elevated the entire composition from loungewear to evening territory, maintaining the citrus palette while adding necessary verticality. Beneath her jacket, her signature stack of rings—including that unmistakable diamond engagement ring from husband Justin Bieber—caught the light, adding just enough sparkle without overwhelming the narrative.

With her hair blown out into natural, windswept waves and dark sunglasses shielding her gaze, Bieber embodied that elusive quality fashion insiders covet: effortlessness with intention. Her dewy makeup completed the picture of studied nonchalance.

Seated alongside Zoë Kravitz and other distinguished guests, Bieber watched as Anthony Vaccarello unveiled his latest vision against the backdrop of the monumental Yves Saint Laurent logo sculpture—a setting that transformed fashion presentation into cultural theater. Her presence and styling tapped into the broader discourse of performance fashion, where the demarcation between runway spectacle and street reality continues to dissolve.

This appearance marks another chapter in Bieber’s enduring romance with Saint Laurent. As a longtime ambassador and campaign star—most recently fronting the Fall 2025 campaign alongside Rosé, Bill Skarsgård, and a constellation of the house’s chosen family—she continues to embody the brand’s particular brand of Parisian rebel sophistication. Monday’s look was simply the latest reminder that in Hailey Bieber’s world, there are no rules—only opportunities for reinvention.
