Now we know: Naomi Biden wore Ralph Lauren at her South Lawn wedding ceremony. She looked elegant in a long-sleeved gown, with a long veil and train. She kept her accessories simple, wearing a pair of Tiffany diamond and pearl drop earrings, and carried a bouquet of white flowers. Her wedding band was Tiffany as well—as was Neal’s band. He paired it with a Schlumberger single daisy brooch.
