Since Robert likes surprises and details, Diana looked for a dress that was a little unexpected but still classically beautiful. She found exactly what she was looking for: a stunning Oscar de la Renta gown. She loved the pale blue train and ruffles that moved like ocean waves when she walked, not to mention the elegant lace overlay. “When I wore it after the final fitting, I felt like me, how I wanted to feel in a wedding gown,” she says.
