The first time Hayley Sullivan and Deven Marrero laid eyes on each other was while serving as bridesmaid and groomsman at a mutual friend’s New Year’s Eve wedding in 2021. “The morning of the wedding, I was enjoying breakfast with my dog, Finn,” says Hayley, the founder of Styled by Collective. “Across from us, Deven offered Finn a piece of bacon — a simple gesture, but one that spoke volumes. The world seemed to narrow to just us three. [Deven] told his friends that day that he would someday marry me.”
Fast-forward to their first date in New York, where a walk in Central Park led to a trip to the emergency vet when Finn got sick. “Deven sat with me on the veterinary floor for seven hours while we waited for an update. It wasn’t the first date I had imagined, but it told me everything I needed to know about him,” she says of the former professional baseball player. “The next day I changed his name in my phone to ‘Deven ∞.’ ” In December 2023, Deven took Hayley to an Infinity sculpture in Napa Valley and asked her to spend forever with him.
The couple wed on January 25, 2025, before friends and family at San Francisco City Hall. To toe a careful balance between grand and intimate, wedding planner Shannon Leahy softened the striking stone walls and marble staircase with dark greenery and cream florals to bring warmth and romance to the palatial space. After the pair exchanged vows, guests moved to the Mayor’s Balcony for cocktail hour and then to a candlelit dinner, where they listened to music by Rhythm Collective from Élan Artists.
The wedding date was also carefully considered. “On our wedding night, a rare celestial event unfolded: a planetary parade, where every planet in our solar system aligned in a single line,” Hayley says. This cosmic phenomenon inspired the pair to weave astrological motifs into the details, including personalized zodiac plates for each guest and arranging the dinner tables to represent the sun with surrounding planets in orbit.
For the after-party, guests were led to the North Light Court, which was draped in burgundy to reconstruct the couple’s favorite lounge at Hôtel Costes in Paris. “We wanted a space that felt like the world’s chicest bar,” says Hayley, who changed out of her custom Dior Haute Couture gown into a beaded dress from the Dior Cruise 2025 collection.
“[The evening] truly felt like a dream —beautiful, magical, and deeply personal,” she says. The couple’s home had burned down just two weeks earlier in the Pacific Palisades fire, so the celebration was particularly emotional. “Our wedding came at a time of personal loss,” Hayley says. “But the memories with our family and friends are the shining light that we will always have.”
