More tight shiny men's pants at #25 (Ricky Martin). Justin Bieber also models the comically male, spoofing adulthood, I think, doing bagginess instead of tightness, at #36. Katy Perry, at #40, seems to be spoofing the old mishap of unwittingly dragging toilet paper with you out of the bathroom. Rihanna, at #47, seems to have collected all that toilet paper and crimped it into millions of tiny ruffles to band around her body in stripes — alternating with — apparently! —nakedness.
It's the Grammys. It's perfectly apt to dress as a joke.
