Hailey Bieber nails garden wedding dress code at Finneas O’Connell’s big day

Hailey Bieber turned heads at Finneas O’Connell and Claudia Sulewski’s star-studded wedding, proving once again that she knows how to make a statement with her fashion choices.

The Rhode founder attended the romantic celebration alongside her husband, Justin Bieber, as Finneas married his longtime girlfriend in Montecito, California, on August 29.

For the garden-themed celebration, Hailey embraced the dress code with a striking citrus-green gown. The backless halter-style dress featured a dramatic plunging neckline, ruched detailing and a flowing skirt that gave her look an elegant yet eye-catching finish. She completed the outfit with peep-toe heels, diamond earrings, an olive-green Gucci bag and a sleek updo. (InStyle⁠)

Justin, meanwhile, opted for a more classic look. The singer wore a three-piece black suit with a crisp white shirt, sunglasses and his signature gold hoop earring. Together, the couple made a stylish appearance as they joined the celebrations.

The wedding itself was equally impressive. Finneas, who is widely known for his work with his younger sister Billie Eilish, married Claudia after the couple spent around eight years together. They first met on a dating app in 2018, and their relationship quickly became an important source of inspiration for Finneas’ music. He even wrote his song “Claudia” shortly after meeting her.

Claudia also made a major fashion statement throughout the wedding weekend. The bride wore several custom Oscar de la Renta creations, including an elegant ceremony gown. Her multiple looks helped create a sophisticated and romantic atmosphere for the celebration. (People.com⁠)

Other notable guests included Kristen Bell, Dax Shepard, Nina Dobrev, Emma Chamberlain, Rachel Sennott and Jason Sudeikis. Billie’s boyfriend, Nat Wolff, was also reportedly among those attending. (EW.com⁠)
