A second appearance from Rihanna in this round-up, but a worthy one. One of the most interesting things about the Met Gala is seeing the creative ways that each guest interprets the theme. While many completely ignore it, Rihanna always goes above and beyond in an effort to commit; 2018 was a case in point when she arrived at the Catholicism-themed event in a glorious Papal-inspired Margiela ensemble.
