4.Princess Grace Kelly Of Monaco And Prince Rainier – 1956
Oscar-winning actress Grace Kelly might have been used to wearing glamorous outfits for Hollywood premieres, but her wedding day was a new level of fashion. When she married Prince Rainer III, she wore a gown designed by MGM costumer, Helen Rose.

It was the ultimate fairy princess look, and Grace Kelly looked like a million dollars. It was the only royal wedding dress designed by a Hollywood costume designer, but it was nothing short of perfection. It featured 125-year-old lace and hand-sewn pearls as finishing touches.
