Celebrities -- they've got a lot going on, but does that excuse that some of them seem to always forget just one piece of clothing? Let's take a look at the repeat offenders.
For Miley Cyrus that item is pants. A high-waisted pantsless look for a June 2013 appearance on "Jimmy Kimmel Live"; in October 2012 -- pantsless with a ghost ... as you do; and sometimes going pantsless means you have to wear what looks a lot like a diaper.
But Miley's not the first to be pantsless and proud . Remember all those Christina Aguilera performances on "The Voice"?
And that other necessary female undergarment -- the bra! Who's famous for forgetting?
It wouldn't hurt Rihanna to remember her brassiere either, though for her, the no bra becomes more of a sideboob issue. Her frequent sideboob has become quite the headline maker, even prompting speculation that sideboob is the new cleavage.
Still, it's not just gals who get forgetful -- guys do too.
The legendary offender, Matthew McConaughey, always, always forgets a shirt (not that anyone’s complaining). Seemingly more offensive? Justin Bieber has become Matthew’s protege, so much so that he's angering fellow celebrities -- Olivia Wilde Tweeted at him to put a shirt on.
But McConaughey actually gave the Biebs his blessing, and we can't very well argue with that ... mostly because we want Matthew McConaughey to keep going shirtless.
