What does a consummate party giver do to mark one of the biggest days of her life? Well, if you’re Iraq-born, London-based Rena Sindhi, you throw the international destination wedding of the summer. To celebrate her marriage to fiancier Markam Abboud, she hosted a five-day extravaganza in Beirut. For the June 29 ceremony, nearly 500 beautifully-attired guests (the dress code was suits for men; long, flowy dresses for the women) gathered at the Orchid Beach Club by the Sea, and the list included Kathy and Rick Hilton, Ulla Parker, Inga Rubenstein, Nick Candy, Bronson van Wyck, Dennis Basso, Serena Boardman, Eva Lorenzotti, Adam Lippes and Christian Louboutin. The bride, clad in a custom blue Roberto Cavalli Haute Couture confection, was joined by her two daughters in custom Cavalli gowns at the sea-inspired affair, which featured a shell, coral, turquoise and white decor theme and a buffet dinner featuring Lebanese specialties.
