Blake Lively has been delighting us with one incredible style moment after another this week!

The 30-year-old has been pulling-out all the stops on the promotional trail for her new film, All I See. Heck, she even wore seven looks in one day on Monday!

However, she saved her best look for last, stepping out in a vintage dress from Chanel's spring / summer haute couture show.

The self-styled star also shared this beautiful close-up on Instagram!

Blake isn't the first person to wear this *exact* gorgeous metallic dress either! It was previously worn by Grace Kelly's daughter Caroline, Princess of Monaco (left). A cool fact first noticed by Town&Country. Moreover, Caroline also lent the one-of-kind dress to her daughter-in-law, Beatrice Borromeo, who's married to her dashing son (Grace Kelly's grandson) Pierre Casiraghi.
