The couple wrote their own vows, and Rebel's niece, Sovereign, presented the bride with rings so they could exchange them. "We hadn't heard each other's vows until the ceremony, so it was really emotional to hear what we had written," Ramona said. "[And when the ceremony was over], we felt so happy and grateful that all of our family and friends could come with us to Sardinia." At the end of the 30-minute ceremony, the brides kissed and left to Natalie Cole's "This Will Be (An Everlasting Love)" as guests cheered them on and threw white rose petals.

After the ceremony, guests were taken by van to the nearby Pedri Garden restaurant, where the reception was held. There, stringed instruments were played as they arrived, and an area with plush sofas and armchairs was created. Inside, the dining room was decorated with white roses, with a modern performance stage for the band and a separate dessert room created specifically for the event. Guests were treated to a variety of fresh Italian food: burrata, a variety of salads, homemade ravioli and risotto, with chicken and Dover sole served as main courses.
Both brides wear very little jewelry in real life, so they opted for timeless Tiffany & Co. rings. Ramona also wore a bejeweled headpiece, and Rebel wore a decorative brooch, both from Pronovias. Rebel's hair and makeup were done by her London-based glam team, with hair by Mikey Kardashian and makeup by Jey Calderbank, while Ramona's hair and makeup were done by Lena Yasenkova. The ceremony began at 5:30 p.m. on the breezy waterfront of the Cala di Volpe Hotel. A floral arch was erected at the end of the aisle for the bride to stand under, and Rebel and Ramona's families were seated in front on either side of the aisle. Four live violinists played live music for the bride as she walked down the aisle. Rebel's best friend Nicholas was the host, and the couple's 22-month-old daughter Royce and Rebel's granddaughter Sovereign were the flower girls. Rebel said of Nicholas: "As a barrister in London, he was always relied on to entertain a crowd because he was a great speaker."
