Hailey Bieber delivered a vibrant black-tie moment while attending Finneas O’Connell and Claudia Sulewski’s wedding with husband Justin Bieber.
The Rhode founder selected a citrus-green halter gown for the couple’s August 29 date night in Montecito, California. Against the ceremony’s lush garden setting, Hailey’s bold color choice looked perfectly suited to the storybook celebration.
Justin took a more traditional approach in an all-black suit, allowing his wife’s dramatic gown to command attention.
Hailey Wore a Plunging Green Gown
Hailey’s floor-length dress featured a plunging neckline that extended past her rib cage. A single halter strap supported the ruched triangle cups, while the fitted bodice transitioned into a voluminous skirt.
The fabric moved around Hailey as she walked, giving the otherwise sultry design a romantic, ethereal quality.
She paired the gown with peep-toe heeled sandals, diamond earrings and an olive-green Gucci handbag finished with a gold clasp. Even her drink matched the evening’s color story: Hailey carried a cocktail garnished with a fresh lime wedge.
For her beauty look, the 29-year-old model swept her long brunette hair into a sleek updo with a subtle center part. Rosy makeup and a soft pink lip complemented the vivid gown without competing with it.
Justin Chose a Classic Black Suit
Justin accompanied Hailey in a black suit and matching tie layered over a crisp white shirt. He finished his outfit with black sunglasses and a gold hoop earring.
Additional photographs showed the singer taking a phone call while Hailey chatted with Billie Eilish, who officiated her brother’s ceremony.
Billie followed the romantic dress code in an off-the-shoulder corset gown featuring a satin olive-green skirt. The muted shade coordinated naturally with Hailey’s brighter citrus ensemble.
Other celebrity couples were also present for the garden wedding, turning the intimate celebration into one of the weekend’s most fashionable events.
Finneas and Claudia Celebrated Their Longtime Romance
Finneas and Claudia married after dating for approximately eight years. The musician and content creator began their relationship in 2018 and announced their engagement in September 2025.
Their Montecito ceremony was surrounded by greenery and floral details, creating an elegant backdrop for the couple and their famous guests.
Billie played an especially meaningful part in the day by officiating the ceremony and standing beside her older brother as he entered his next chapter.
Hailey and Justin have also spent years navigating major milestones together. They legally married at a New York City courthouse in September 2018 before holding a larger religious ceremony in South Carolina the following year. Their latest wedding appearance arrived just before their own eighth anniversary.
Hailey and Justin Recently Celebrated Their Son
The wedding date came one week after Hailey and Justin celebrated their son Jack Blues’ second birthday.
The proud parents shared behind-the-scenes photographs from the toddler’s birthday party. Hailey also marked the emotional milestone by posting a black-and-white photograph of her baby bump from her pregnancy.
Hailey and Justin welcomed Jack in August 2024, nearly six years after they married.
From celebrating their son at home to dressing up for a romantic garden wedding, the couple has had a milestone-filled month. Hailey’s citrus-green gown ensured their latest date night was also one of their most memorable style moments.
