Miley Cyrus' insane outfit at the iHeartRadio Music Festival

While everyone in Hollywood was getting glammed up to go to the Emmys, putting the last style tweaks on their ballgowns and ensuring their updos and blowouts looked just right, Miley Cyrus was in Las Vegas wearing this.

As far as we can tell, it consists of: black nipple pasties, a white mesh dress, black and white underwear/bathing suit bottom (pretty sure it's this Agent Provacteur bikini bottom) and a Yeti fur shrug.

To be fair, Cyrus wore the getup onstage, performing at the iHeartRadio Music Festival–a performance, which seemed to be inspired by a psychadelic drug trip. There were dancing mushrooms, people dressed as flowers and grass, a rainbow in the background; at one point Cyrus slapped a dancing little person on the ass. If the theme of performance was a mushroom trip then we guess Cyrus's outfit is actually kind of perfect.

Still, we have a few questions for Cyrus. Like, why? And, no seriously, WHY!? We get that she's trying to rebel–and we've actually really appreciated a lot of the fashion risks she's taken thus far. But this latest outfit is just perplexing–at least to this humble writer. Do you think Cyrus went too far? Or am I getting old, and just not understanding kids these days?

The silver lining in all of this is that Cyrus just gave Cheryl the perfect Halloween costume.
