Instead of a traditional white wedding gown, Diana chose a beach-appropriate empire-waist Beth Bowley for BHLDN dress covered in coral- and smoke-colored zinnia flowers. "We ended up planning the entire wedding around it!" says the bride. And it paid off: The romantic, vintage, and fun vibe of the wedding reflected Diana's casual, yet showstopping dress. "We wanted an authentic Hawaiian feel with vintage flair," she says.
