HGD Stephanie's wedding dress sketch by Elie Saab

Countess Stephanie of Belgium (now Princess Stephanie) married Prince Guillaume of Luxembourg in a dazzling two-day ceremony, wearing a jaw-dropping Elie Saab gown which featured a cathedral-length veil and a train for days. True to form, the guests—many of them royalty themselves—put on their best finery to celebrate the royal couple.

Over the weekend, Countess Stephanie of Belgium and Prince Guillaume of Luxembourg married in a lavish two-day ceremony. Read on to see her gorgeous gown and the spectacular hats worn by some of the guests!

A low-set chignon twisted around her glorious ivory silk tulle veil. Hair stylist Tom Marcineau of the House of Carita in Paris made sure the Princess' blonde locks were firmly in place, crowned only with a glistening Altenloh de Bruxelles tiara. The leaf motif of the dress complemented the design of the diamond headdress – which has been passed down by her family since 1878.
