Pop stars and more congregated at the IHeart Radio Festival in Las Vegas this weekend, looking wild and crazy in their ensembles. It's a live festival, so attire was loose and casual (unless you were Diddy), and they were able to push the boundaries of fashion. Like Katy Perry, who had strange bun-like appendages sitting atop her head, did. Meanwhile, Miley Cyrus paired a revealing, bathing suit-like stage outfit with sneakers.
She also went Gaga -- literally -- with her white mesh/netted "dress" over black pasties and dominatrix-like undies.
See our recap of red carpet walkers and their cray cray ensembles.
Katy Perry rocked Princess Lea buns + strappy heels.
Can she communicate with life on other planets via those buns?
The man in black ... Robin Thicke. Is a single hair out of place? Nope.
A hybrid of dominatrix beachwear for Miley. Risque and anything but modest.
