This weekend, Instagram was abuzz with snaps of society's finest celebrating the nuptials of Hayley Bloomingdale and Dada Stileman. A gorgeous, flower-filled church ceremony followed by a reception at the très chic Four Seasons hotel Biltmore in Montecito, California.

 Guests included the likes of Indre Rockefeller, Lauren Santo Domingo, Valerie Macaulay, and more fabulous names. Click through for a look at the sweet affair!
