Katy Perry’s look at the 2017 Met Gala was one of the most talked-about of the night. The singer wore a custom-made Maison Margiela ensemble by John Galliano, complete with a red tulle dress, embroidered coat, and a veil with a headpiece that spelled “Witness.” The look was criticized by some for being too over-the-top, but it undoubtedly made a statement.
