We've come to expect wild costumes from Miley Cyrus at this stage, and even if she walked out on stage totally naked we probably wouldn't bat an eye.

But for the opening night of the Miley Cyrus and her Dead Petz tour in Chicago last night, the singer reached all-new levels of NSFW.

Strolling on stage sporting a huge fake penis strapped to her crotch, plus a dominatrix-style leather and metal harness, Miley left very little to the imagination.

Cripes.

Of course, this is most definitely not the first time the former Hannah Montana star has bared all. Here's a look back at some of her craziest looks to date…

1. There was the giant inflatable penis at G-A-Y Club in London

 

2. The infamous nude pleather look for her 2013 VMA performance with Robin Thicke

 

3. Then there was her risqué photoshoot with Terry Richardson 

 

4. And another shoot with Terry for Candy magazine just last month

 

5. And finally, who can forget her Wrecking Ball video?
