Or should it?
I suppose it depends on the body wearing it.
In this case, Pink, is looking pretty buff from her aerial workouts and deservedly wears it well. Here's some pics and video of her cradle act as performed on the MTV awards.
She does a very nice job, pointed toes, catches and all while singing.
I guess it's not enough nowadays to simply sing. In order to hold people's attention you have to risk life and limb, or at least appear to, as well. Seems to be a trend going on here. I suppose it comes with being a type "T" as in Thrills personality. Better the thrill of an aerial workout than drugs and alcohol.
You go girl!
