We wonder what shocked fans more about Katy Perry's impromptu performance with BF John Mayer—the fact that the super busy artist found time to stop by or the fact that she came dressed like a 50-year-old business woman?!

Not to rain on this cool concert moment parade, but why is the "Roar" singer so conservatively dressed? Did she literally go from an uptown meeting with her financial planning team to this Brooklyn music venue? Because that's what this outfit suggests.

Not only is this dress funeral black and way longer than the edgy dresser typically wears, but it's covered in a floral print, fit for a living room couch. And to make matters more elderly, she's wearing it with opaque black tights!

Maybe the "Who You Love" singer wanted to keep the focus squarely on her main man? If so, wrong choice. There's no way the crowd could focus on anything but the crooner's old lady!
