Katy Perryâs Met Gala Dress Is being Criticized. Perryâs gown was definitely in the âArt of the In-betweenâ themed realm, but for some was a bit much and created by John Galliano. âThe Dali Mailâ was among those who dubbed her the Worst Dress, though âVogueâ, whose Editor-in-Chief puts together this event, added her to their best dressed list. BTW, it had a 10-Foot Train ... You be the judge!
