Singer Billie Eilish made a striking fashion statement at the after-party of her brother Finneas O’Connell’s wedding, opting for a sophisticated plunging satin slip dress. The Grammy-winning artist, who also served as the officiant for the ceremony, changed into a new ensemble for the post-nuptial celebration, showcasing a different facet of her style.
Billie Eilish’s After-Party Ensemble
Following the main ceremony and reception, Billie Eilish transitioned from her custom green corseted gown to a floor-length, chocolate brown satin slip dress. The design featured delicate spaghetti straps and a dramatic plunging neckline, exuding an air of understated glamour. She kept her accessories minimal, allowing the dress to be the focal point, and wore her hair down, cascading to her shoulders. This second look was perfectly suited for her performance during the after-party, where she joined her brother on stage to perform their recent hit, “Birds of a Feather.” The choice marked a departure from her more structured, custom ceremony attire, highlighting her versatility in both fashion and performance.
Finneas and Claudia Sulewski’s Nuptials
The wedding of producer and musician Finneas O’Connell and his longtime partner, YouTuber Claudia Sulewski, took place on August 29 in Montecito, California. The couple, who have been together since 2018, celebrated their union with a ceremony followed by a reception that blended a romantic garden setting with a rustic backyard ambiance. The event was attended by close friends and family, including their beloved rescue dogs, Peaches and Mousse, who were adorned with custom Oscar de la Renta bows matching the bride’s gown.
A Celebration of Style: Multiple Dresses and Designer Tributes
Claudia Sulewski was the undeniable sartorial star of the day, showcasing an impressive collection of four custom Oscar de la Renta gowns. Her ceremony dress was a magnificent white silk ballgown, complete with a dropped waist, a voluminous pleated skirt, and the practical addition of pockets. For the rehearsal dinner, she chose a sleek, backless white satin columnar gown. A sculptural white gown with a feathered peplum was worn for the reception, during which she shared her first dance with Finneas. The after-party saw her in a chic ensemble featuring a baby pink top paired with a structured grey bubble skirt and matching heels.
Finneas, a collaborator with his sister Billie Eilish on numerous hits, was impeccably dressed in custom suits by Prada throughout the festivities. The wedding itself was a deeply personal affair, with details curated to reflect the couple’s journey and preferences.
Intimate Moments and Musical Performances
The bride recounted a serene wedding morning, despite having only a few hours of sleep due to the excitement. A particularly cherished moment was the “first look” with Finneas, captured in her bridal suite. “A moment I’ll never forget,” Sulewski shared. Following portraits with family, the couple proceeded to the ceremony, where Sulewski walked down the aisle to a special rendition of “Angel,” performed by Finneas.
The exchange of vows was accompanied by soft musical arrangements, culminating in the couple holding their dogs as they concluded the ceremony. The reception featured a cake-cutting ceremony set to a Daft Punk track. A highlight of the evening was a performance by singer Leslie Feist, a favorite artist of the couple. Feist performed “One Evening,” a song particularly meaningful to the couple. “Leslie was the second person Finneas called after his sister when we started planning our wedding,” Sulewski expressed, “and she sang all of our favorite songs that night. A complete dream come true that we kept having to remind each other was our reality.” The presence of close family, including Billie Eilish’s role as officiant and performer, along with personal touches like custom attire and meaningful musical performances, underscored the intimate and joyous nature of Finneas and Claudia Sulewski’s wedding celebration.
