Singer-songwriter Finneas O’Connell and actress Claudia Sulewski are officially married. After eight years together, the couple exchanged vows on August 29 in California, surrounded by family and friends for an intimate celebration. Adding an especially meaningful family touch to the day, Finneas’s sister, Grammy-winning singer Billie Eilish, officiated the outdoor ceremony. For her walk down the aisle, Sulewski chose a custom Oscar de la Renta creation. Her bridal wardrobe extended well beyond the ceremony, with custom Oscar de la Renta looks designed for the rehearsal dinner and reception, each bringing its own take on modern bridal glamour.
The celebrations began long before the wedding day. Rather than a traditional bachelorette party, Sulewski joined Finneas and their closest friends and family for a co-ed bach trip in Mexico, where a lineup of effortlessly chic looks showcased her signature approach to bridal style. Alongside her pre-wedding wardrobe, her engagement portraits and wedding-weekend ensembles offer an inspiring study in contemporary bridal fashion — from understated and romantic to polished and statement-making. Ahead, discover bridal dresses and accessories inspired by Claudia Sulewski’s most memorable wedding-weekend looks.
Claudia Sulewski’s Vintage
Bridal Shower Look
For her bridal shower, Claudia Sulewski leaned into a softer, old-school kind of romance. The look centered on a vintage 90s dress from Happy Isles: a beige-cream tea dress with romantic short sleeves, a flattering V-neckline, and delicate beaded florals scattered across the fabric. Neutral heeled sandals kept the palette understated, while a petite beaded tassel cream bag with touches of purple introduced an unexpected hint of color. The result felt timeless without looking overly traditional — a refined take on engagement portrait style that lets the details do the talking.

Bachelorette Style in Mexico
Sulewski’s Mexico bach trip traded the expected bachelorette formula for a decidedly cooler vacation wardrobe, spanning several celebrations and laid-back getaway looks. Among the standout pieces was a pearl-shell mini dress styled with oversized bangles and a matching pearl-shell clutch, bringing a touch of mermaid glamour to the festivities. Elsewhere, she opted for an racer-back ivory gown, a crochet-detail mini dress complete with a flower-embroidered veil. Together, the looks capture a more fashion-conscious approach to bachelorette style, where bridal details meet the relaxed spirit of a sun-soaked escape.

Oscar de la Renta Rehearsal Dinner Look
For the rehearsal dinner, Claudia made a case for simplicity with a custom Oscar de la Renta silk gown that revealed its impact from the back. Cut on the bias from liquid crepe back satin, the white dress followed the body with an elongated, fluid silhouette before opening into a dramatically bare back. Its defining detail was the neckline draping, which swept downward and extended all the way toward the lower back. Rather than competing with the setting or the rest of her wedding wardrobe, the minimalist design offered a quietly sensual opening statement for the celebrations to come.

Oscar de la Renta Wedding Ceremony Look
For the ceremony, Claudia Sulewski embraced the grandeur of a classic bridal ballgown with a distinctly modern Oscar de la Renta finish. Her custom ivory silk faille gown featured a sculpted drop-waist, corseted bodice and dramatically structured pleated skirt, with subtle draping defining the waist. The most distinctive element was the asymmetric scarf neckpiece, carefully draped and pleated to stream down the full length of the train, transforming the traditional silhouette into something far more fashion-forward. She completed the Oscar de la Renta wedding dress with a long tulle veil secured to a sleek, polished hair bun, creating a striking contrast between the clean styling and the volume of the gown.

Oscar de la Renta Reception Look
Claudia shifted the vibe for the reception, trading the sculptural volume of her ceremony gown for a more unexpected evening silhouette. Her custom Oscar de la Renta look was crafted in structured cady and defined by a sculptural peplum made entirely from upcycled feathers. Crystal beading was scattered throughout the feather detailing, catching the light and adding a subtle sense of sparkle to the otherwise architectural design. The combination of sharp construction, tactile texture, and embellished feathers gave her reception look a distinctly modern after-dark character — proof that bridal style can be just as expressive once the vows are over.
