Princess Stephanie of Luxembourg and her brother Count Jehan de Lannoy arrive at her wedding to Prince Guillaume of Luxembourg at the Cathedral of our Lady of Luxembourg on Oct. 20, 2012, in Luxembourg. The bride wore a custom couture Elle Saab gown heavily embroidered with pearls, beads and silver thread. The ivory gown had a bateau neck, three-quarter-length lace sleeves and a long train. Her long, lace-trimmed veil fell from the Lannoy family diamond tiara. Made by Altenloh in Brussels, the tiara was previously worn by the princess' sisters and sisters-in-law on their wedding days.
