Leah Isadora Behn made a characteristically playful entrance at Copenhagen Fashion Week this week. The shirt’s message carried an extra layer of humor given exactly who her mother is: Princess Märtha Louise of Norway. Leah is the second of three daughters born to the princess and Ari Behn, an author and artist. (Behn and Princess Märtha Louise divorced in 2017, and Behn died in 2019.) Copenhagen Fashion Week has become a regular fixture for Leah, who has built a profile in the fashion and beauty world that stands entirely on its own.
