12 Royal Wedding Guests Who (Almost) Outdressed the Bride

Just days before her own royal wedding in 2004, Letizia attended the marriage of Crown Prince Frederik of Denmark and Mary Donaldson in Copenhagen on the arm of her then-fiancé, Felipe of Spain. This major wedding was her debut in front of European royalty, and Letizia brought the wow factor with a Caprile dress matched with heirloom rubies and diamonds that almost took Mary off the front pages.

Weeks after returning from honeymoon, Felipe and Letizia attended the wedding of his cousin, Luis Gomez-Acebo, and model Laura Ponte, which took place in Segovia. While the bride wowed in a '30s-style wedding dress, newly royal Letizia grabbed everyone's attention in this standout ensemble featuring an embellished skirt and fitted jacket.

Letizia came close to being outdressed at her own wedding in 2004 in Madrid, by the royal style icon she would end up being compared to most often. Queen Rania of Jordan attended the ceremony at the Almudena Cathedral in a lilac and white two-piece featuring a full-length skirt and shirt-style top. Letizia's own early gala style after her marriage bore a striking resemblance to this knockout look.

Who needs a tiara to wow when you've got a dress this good? Queen Maxima of the Netherlands got everyone gasping when she attended the wedding of her brother, Juan Zorreguieta, to Andrea Wolf in this embellished lilac ballgown. While her daughters were bridesmaids at the ceremony, which took place in Vienna, their mom had her own fairy-tale moment with this extravaganza of a dress.

No one does chic like Caroline! She chose this caramel dress with just enough gold to get everyone sparkling for the wedding of Hereditary Grand Duke Guillaume of Luxembourg and Stephanie of Lannoy in 2012. From the hat with a hint of a veil about it to the clever embellishments on the dress, this is a standout look that very nearly outshone stunning Stephanie.

Knockout wedding outfits clearly run in the family because Caroline's daughter, Charlotte Casiraghi, was grabbing all the looks when she attended the wedding of her uncle, Prince Albert II of Monaco, and Charlene Wittstock in 2011. Charlotte was pretty in pink with just enough edge to make this look stand out from the crowds.

Before she was even a royal, Charlene of Monaco had nailed the princess look. The wedding of Crown Princess Victoria of Sweden and Daniel Westling, in Stockholm in 2010, was billed as the biggest since Charles and Diana said "I do," and Charlene was more than ready for her close up. She chose a pale mushroom strapless gown with a diaphanous shawl that had just the hint of bridal about it. And no wonder. Just days later, she and Albert announced their own engagement.

Kate was just a newlywed herself when she dazzled at the wedding of Zara Phillips. Prince William's cousin married Mike Tindall in Edinburgh in 2011, but just as many eyes were on Kate as she made one of her first appearances as a full-fledged royal. She chose a cream coat dress and statement hat for the ceremony and grabbed almost as much attention as the bride.

Marie-Chantal knows a thing or three about fashion, so there were no surprises when she turned up in a seriously standout look for the wedding of her brother-in-law, Prince Nikolaos of Greece, and Tatiana Blatnik at Spetses in 2010. A host of European royals attended the event, but all eyes were on Marie-Chantal in this rose-pink gown with embellished shawl.

Before meeting Letizia, Felipe of Spain was supposedly at the point of proposing to Norwegian model Eva Sannum. When she attended the royal wedding of Crown Prince Haakon Magnus of Norway and Mette-Marit Tjessem Hoiby in Oslo in 2001, the rumor mill went into overdrive. But it's safe to say her presence would have made all the headlines even without engagement rumors after she wore this unforgettable blue gown with matching shawl and gloves to the event. She and Felipe parted company a few months later.

You either love or hate this outfit chosen by Infanta Elena of Spain for the marriage of Crown Princess Victoria and Prince Daniel in 2010, but there's no denying it's a scene-stealer. From the bolero jacket to the gown's knock-you-sideways-pink hue, this is a dress to remember . . . and then some. The fact that it's still being talked about eight years after the wedding shows just how close it came to stealing the spotlight from the bride herself.
