With delicate beading and an unexpected open-back detail, Kristen's white lace Jasmine Galleria dress was the epitome of vintage glamour. "That gown encapsulated everything that I wanted in a wedding dress," she says. "It didn't take long to realize that once I put it on, it was the one." Our favorite detail? Gold detailing that perfectly reflected the Kristen and Alex's gilded "Great Gatsby" theme.
