In all fairness, we'd be lost dressing for a Björk concert too.
It looks like Katy Perry went with a goth girl costume from the ‘90s, the era that made the Icelandic sensation famous. Or is Katy just planning to practice some witchcraft at a go-go bar later on in the night?
We're not sure what inspired the "Wide Awake" singer's dark tights, mini skirt and cross emblazoned top, but the long overcoat definitely makes the look coven-ready. We know one thing: We prefer Katy in a color—any color!—to drab black from hair to toe.
Maybe we should just be thankful that Katy didn't honor Björk with the famous swan dress?
