Pieter Mulier stepped into the role of creative director at Alaïa in 2021 with big shoes to fill after Azzedine Alaïa’s passing. What he delivered over five years was a fresh fusion of sculptural futurism, sensual body-hugging fits, and clever nods to the house’s archives that made stars line up to wear it. From red carpets to casual outings, his designs turned heads and sparked conversations, proving Alaïa could feel both timeless and totally now. If you’re hunting for the standout celebrity moments that defined his era, you’re in the right place.
Mulier arrived with serious credentials from working alongside Raf Simons at Dior and Jil Sander, but he quickly made Alaïa his own by blending precision tailoring with playful volume. He kept the brand’s signature cling and curve-enhancing cuts while adding modern twists like padded hips and mesh details that felt fresh yet faithful. Celebrities noticed immediately because his pieces flattered real bodies without apology, and that authenticity is what kept the buzz alive until his emotional farewell show in March 2026.
What set Mulier’s Alaïa apart was its mix of high drama and everyday wearability that let stars shine without trying too hard. Actresses loved the sculptural shapes for photos that popped on every feed, while musicians turned to the sensual knits for stage presence that screamed confidence. You could feel the emotional pull in how these looks celebrated femininity in all its forms, making fans root for more long after the runway lights dimmed.
Zendaya jumped on the Mulier bandwagon early and never looked back, turning Alaïa into her go-to for major moments. Her choices always felt intentional, mixing bold exposure with elegant tailoring that highlighted her effortless cool. Whether it was a photocall or premiere, she made every piece look like it was custom-made just for her vibe.
That ab-baring plum crop top and furry mermaid skirt from Mulier’s debut Spring 2022 collection stole the show at Zendaya’s Dune Paris photocall. The cutouts and texture play showed off Mulier’s knack for blending sexy with sculptural, and Zendaya wore it with that signature poise that made the whole look instantly iconic. It was the perfect launchpad for what was to come from the new Alaïa era.
Rihanna didn’t just wear Alaïa by Mulier; she lived in it through pregnancies, performances, and private dinners, proving the designs could handle real-life glow-ups. Her choices highlighted the brand’s versatility, from high-shine stage armor to soft maternity-friendly cutouts that felt empowering rather than restrictive. No wonder she became the face of his tenure—her confidence elevated every silhouette to legend status.
For the 2023 Super Bowl, Rihanna rocked a cherry red jumpsuit with a glossy breastplate that screamed power and playfulness all at once. Mulier’s take on futuristic shine met her bold energy perfectly, turning a performance into a fashion event that fans still talk about. It was pure Mulier magic: technical enough to move on stage yet sexy enough to own the spotlight.
At the Highest 2 Lowest Cannes premiere, Rihanna’s aqua cutout-riddled dress hugged her bump in the most flattering way, thanks to Mulier’s clever draping that celebrated curves instead of hiding them. Later, her hip-padded skirt and hooded crop top for a simple Giorgio Baldi outing showed how his designs worked for everyday glamour too. These looks captured the joy of motherhood with zero compromise on style.
Kaia Gerber embraced Mulier’s Alaïa right from the start, wearing body-con pieces that echoed the house’s heritage while feeling utterly modern. Her red-carpet choices highlighted the technical knitwork and gathered skirts that became Mulier signatures. As a next-gen face of fashion, she helped introduce his vision to a younger audience craving sophisticated sensuality.
At the 2022 Academy Gala, Kaia’s sexy turtleneck dress paired with a burgundy gathered skirt showed off Mulier’s mastery of proportion and texture. The fit skimmed her figure just right, proving his designs could be both modest and magnetic. It was one of those moments that reminded everyone why Alaïa under Mulier felt relevant again.
Stars like Selena Gomez, Margot Robbie, and Jennifer Lawrence turned to Mulier’s Alaïa for events where elegance met edge, choosing pieces that photographed like dreams but felt comfortable in real time. From Met Gala twists to film premieres, these women proved the designs translated across body types and occasions. Their repeated wears built a loyal celebrity fanbase that kept the brand buzzing.
Mulier’s collections featured recurring motifs that celebs couldn’t get enough of, from padded hips to waterfall knit skirts that moved like liquid. These elements added volume without bulk, creating that signature Alaïa hourglass while staying true to modern minimalism. Fans still hunt for vintage Mulier pieces because they deliver instant wow factor.
Mulier’s accessories, especially the elongated Le Teckel bag and mesh ballet flats, became must-haves that celebs paired with his clothing for full-head-to-toe Alaïa moments. These pieces offered practicality with high-fashion flair, turning simple outfits into statement ensembles. Their viral appeal helped push Alaïa into mainstream conversations beyond the runway.
Mulier honored Azzedine’s clingy legacy but infused it with Belgian minimalism and Raf Simons-inspired precision that felt less theatrical and more wearable. Where the founder leaned into dramatic cutouts, Mulier added subtle architecture like ribbed waists and cocoon shapes for a quieter power. This evolution kept loyalists happy while attracting new fans who wanted sophistication with a twist.
