Katy Perry is pushing buttons tonight at the Met Gala 2017, and in return, Twitter commenters are pushing keyboard letters as fast as they can type. Wearing a bold red dress inspired by Rei Kawakubo and created by Maison Margiela/John Galliano,
Perry is bringing out all the feels from onlookers. Her headpiece, a bit of a puzzle to solve, reads "eye witness" and is adorned by an eyeball applique and mirrors.

Most fashion mags are loving the "Bon Appetit" singer's look. However, there's a deeper issue with it than the aesthetic. Gown creator John Galliano is known for his extreme anti-semitism, and it's terribly troubling that Perry would choose to support his brand by wearing the dress.
