Rihanna

For China: Through the Looking Glass in 2015, Rihanna wore an enormous yellow fur-trimmed cape by the Chinese couturier Guo Pei that took two years to embroider and needed attendants to carry it up the steps. Three years later, for Heavenly Bodies, she arrived in a jewelled Maison Margiela mitre and minidress, cementing her reputation as the guest who takes the theme furthest.
