Inside Claudia Sulewski and Finneas O’Connell’s Montecito Wedding: From 4 Custom Designer Gowns to Life After Tying the Knot

Claudia Sulewski and Grammy-winning musician Finneas O’Connell are officially in full newlywed bliss following their intimate wedding ceremony in Montecito, California. Reflecting on the milestone two months after exchanging vows on August 29, the 30-year-old actress and CYKLAR Skincare founder admitted that the couple is still riding an emotional high from what she calls the absolute best day of their lives.

The duo, who first connected on a dating app back in 2018 before getting engaged, brought together close family, industry icons, and high fashion for a weekend celebration that left a lasting mark on both of them.

“Oh, we’re blissed out,” Sulewski shared while attending the WWD Honors gala at Cipriani South Street in New York City. “We’re still experiencing the withdrawals of that being the best day of our lives and it now being behind us. But it’s so good. We’re so happy, and just truly, best day of our lives.”

A Journey From Dating Apps to Montecito Nuptials

The road to the altar spanned several years of shared creative projects and high-profile red carpets. After meeting digitally in 2018, their relationship grew steadily out of the spotlight before culminating in an engagement announcement, followed by their August celebration in coastal California.

For Sulewski, the emotional weight of the actual wedding day proved completely unique compared to any other career or personal milestone.

“New feeling unlocked, that’s what I keep saying. The feelings we felt on that day, I have never felt ever in my life before.”

That profound sense of joy translated into every detail of the ceremony, where the bride showcased multiple high-fashion looks crafted exclusively for the weekend festivities.

The Four Oscar de la Renta Bridal Looks

Rather than settling on a single traditional look, Sulewski turned her nuptials into a multi-phase fashion showcase. She wore four different custom Oscar de la Renta designs across the wedding weekend, as documented by Vogue.

During her final fittings at the Oscar de la Renta boutique in Beverly Hills, Sulewski shared a sweet behind-the-scenes moment with her future sister-in-law, pop superstar Billie Eilish.

Sulewski connected with Eilish via FaceTime to reveal the ivory ceremony gown ahead of the big day, prompting an instant reaction from the singer.

“My God, I can’t believe it. You look like an angel. Love you so much!”

Settling Into Married Life and Holiday Traditions

While curating four couture bridal gowns required months of meticulous styling, Sulewski admitted that everyday planning after the wedding takes a much more relaxed approach.

Speaking on seasonal plans like their annual couple’s costume traditions, she noted that spontaneous coordination remains a staple of their relationship dynamic.

“We love doing matching costumes,” Sulewski explained. Rather than starting from scratch, she looked to repurposed pieces from previous plans: “I have a costume from last year that I didn’t end up wearing. And it’s kind of like a black and white, Joker, clown vibe. And Finneas is going to do a king of hearts. So I could be a spades card.”

“It’s going to come together with the makeup,” she added. “So that kind of matches, and that’s what we’re rocking with.”

✨ The transition from a landmark Montecito ceremony to relaxed married routines marks an exciting new chapter for the creative couple.
