Hosting a dinner for the Copenhagen Fashion Summit, Princess Mary had the perfect fashion solution: a timeless and elegant black dress, which she paired with yellow heels that added a pop of color. But while Mary's look definitely wowed us, we couldn't help but think back to another woman who enjoyed similar styles — Audrey Hepburn.

The sleeveless high-low number looked like something the iconic actress would have totally worn, proving once and for all that Mary's a master of classic fashion. Take a look at her ensemble ahead, and then check out a similar one Audrey once wore.
