Alessandra Brawn and Jon Neidich’s Wedding in Pisa, Italy

By 10:00 a.m. on Sunday, June 22, the last of the late-night revelers were piling into cabs and speeding back toward hotels in Lucca and Forte dei Marmi—the final capstone to the three-night extravaganza that was Alessandra Brawn and Jon Neidich’s wedding in Pisa, Italy. Given that the couple met at the Standard High Line hotel (at the time, Brawn worked at the Standard Grill, and Neidich was the managing director of Le Bain and the Boom Boom Room), it’s no surprise that the reception reached bacchanalian proportions. “Throwing a party is totally in Jon’s DNA,” Brawn says. “He loves to host, so he took charge of a lot of the entertaining.”

The 9:00 p.m. ceremony unfolded beneath a giant stone pine tree on the grounds of a family friend’s villa. Aby Rosen and Samantha Boardman’s children, Baker and Vivian, walked down the aisle ahead of the bride, taking their duties as ring-bearer and flower girl seriously. “I’m a professional,” eight-year-old Baker assured the bride, who wore custom Emilio Pucci.

“I don’t consider myself to be an extremely traditional person,” Brawn says, “but the one thing I really wanted was this traditional wedding-dress silhouette, with sleeves and a train. [Emilio Pucci creative director] Peter Dundas managed to be totally timeless and romantic but also kind of sexy, which is, I think, what he does best.” A long veil dotted with lace flowers, pearl-and-diamond drop earrings from her mother-in-law, Brooke Garber Neidich’s, jewelry company Sidney Garber, and Gianvito Rossi sandals finished Brawn’s first look (she later changed into a short, shimmering Emilio Pucci dress and Converse high-tops).

The couple’s 400 guests, each of them dressed in la dolce vita attire, sat underneath hundreds of string lights at two long dinner tables before fireworks got the crowd on its feet to be led by a local band to the dance floor, where the newlyweds swayed to James Taylor’s “Something in the Way She Moves.” Around 2:30 a.m., merrymakers were led to a second site, where event planner Bronson van Wyck and his team helped coordinate a spectacle replete with fire twirlers, contortionists, and a mermaid. As the sun came up, the truly tireless received sunglasses and sweatshirts. “I jumped in the pool around 8:00 a.m.,” Brawn remembers. “At that point I sort of said, ‘OK, now I’m freezing.’ ”
