If there's one thing fans love about a royal wedding, it's finding out what the bride is wearing.
Ever since Grace Kelly and Prince Rainier III of Monaco exchanged vows in 1956, royal couples haven't disappointed in the wardrobe department during their romantic ceremonies.
In addition to wearing "The Spencer Tiara," Princess Diana stunned in her Elizabeth Emanuel dress that featured a 25-foot train. As for Kate Middleton, she earned rave reviews for her gown by designer Sarah Burton.
While Pippa has been spotted shopping at high-end stores including Suzanne Neville in London's plush Knightsbridge, royal watchers still have no idea what the bride-to-be will wear on her big day this Saturday.
With suspense only growing, we decided to take a look back at a few other royal weddings to see what the bride wore.
If predictions do come true and Suzanne is the lucky creator, fans will be delighted to hear that she is an "award-winning designer of bridal and evening wear couture fashion, all British hand-made wedding dresses and gowns."
On the other hand, a source close to designer Giles Deacon's team teased the wedding dress design as "very simple, elegant and it's all handmade."
Like we said, the biggest fashion look of the wedding is still very mysterious.
