In 1985, Princess Diana shared a special dance with @johntravolta at the @whitehouse wearing a midnight blue velvet gown designed by Victor Edelstein. Today, fashion history identifies the iconic dress as simply Alexandra Saint Mleux wearing custom Guerin, inspired by Grace Kelly's iconic blue dress in To Catch a Thief, 1955. One of my favorite looks of hers. #alexandrasaintmleux #gracekelly #gracekellystyle #guerin #vintagefashion # The most beautiful blue dresses in cinema Vogue France The iconic blue dress worn by Grace Kelly in the film To Catch a Thief (1955) is a stunning example of her timeless style!
