Under a canopy of trees late in the afternoon, the bride, 33, dazzled in a Vera Wang sweetheart neck, A-line gown of Chantilly with hand-pieced corded lace appliqué, while her groom, 32, wore a Ralph Lauren Black Label peak-lapel tuxedo and Polo Ralph Lauren bow tie.
Larter walked down a grassy aisle lined with purple, pink and white flowers and carried a simple matching bouquet as guests looked on. The bride wore a pair of satin platform sandals by Jimmy Choo.
They were engaged in December 2007, and later that year Larter, 33, spoke about her husband-to-be saying MacArthur, 32, "brought light to my life. I feel lucky every morning when I wake up and see him."
