Jamie-Lynn Sigler
Why is the former Sopranos star wearing her sleep shirt to a fashion collection launch party in NYC? Talk about a faux pas!
Kate Walsh
The Private Practice star's shirtdress is way more shirt than dress.
Whitney Port
A big white dinner jacket obscuring barely there tap pants...How many different explanations can you come up with for this reality star's funky getup?
Victoria Beckham
Even Posh is aware her clothes are too short—check out that tug.
Kate Hudson
Ugg boots with a teeny-weeny floral slip?! It's pretty sad when Kate's lack of pants actually isn't her biggest problem.
Mariah Carey
A few more inches added to the hemline and this could've been a dress (not a great one, but a dress nonetheless). So close, Mimi!
Mel B
She's no longer a Spice Girl, but she's definitely still scaring people.
Ginnifer Goodwin
This is all you've got, Ginny, a trench coat? We'd suggest putting on some pants before any more people mistake you for a flasher.
Taylor Momsen
It doesn't matter that the sides of this sad sack give a little extra coverage—it's still way too short where it counts most. Put on some pants, sweetie, or you're grounded.
Solange Knowles
Feathered details are fun, but what this tank really needs is an extra few inches of fabric at the bottom.
Jessica Simpson
The teeny-weeny, printed tunic is adorable, but it looks like Jess forgot a bottom to go with it. Chalk this up as another blunder for the fashion-challenged singer.
Rihanna
The gray sweater looks cozy, but even this noted fashion rebel and all-around badass looks odd going out in just a top. May we suggest moving the fringe from the shoulders to the bottom hem for more coverage?
Vanessa Hudgens
Look, V, we know your gladiator platforms are, like, supercute, but c'mon, going out in this getup is not the classiest way to show 'em off.
Christina Aguilera
Xtina shows off her wild side in a cheetah-print onesie, sparking a thousand more comparisons to Lady Gaga in the process.
Lindsay Lohan
Remember when LiLo had that little problem where the police found cocaine in pants she claimed were not hers? Well, the starlet figured out how to avoid that issue entirely.
Lady Gaga
We're not the biggest fans of her wacky pantless style, but the chanteuse practically owns this look, complete with the 'tude to carry it off.
Blake Lively
Gotta wonder how many times people kindly whispered to Blake, "Sweetie, did you forget something tonight?" Because opaque tights, though they cover up the skin, do not equate to pants or any other kind of acceptable bottoms.
Shenae Grimes
A plaid button-up, floral-patterned hosiery, no pants and slouchy thigh-high boots. Four wrongs make...one huge mess! (Which is too bad, because the 90210 star's got potential.)
Lily Allen
So the "Smile" singer isn't wearing a bottom (remember, tights don't count), but the strategically placed Chanel purse is really cute, right?
Pamela Anderson
The mother of two is a repeat offender when it comes to going out pantless. Could this be a sign of a midlife crisis for the former Baywatch babe?
Katy Perry
Poor Katy. Little does the singer know, all eyes are on her not because what she's saying onstage is so captivating but because she forgot to wear the matching slacks to her D&G blazer. Oops!
Lisa Rinna
The fortysomething TV host's bod is still smokin'. But one wrong move in this way-too-mini minidress and she could easily flash her lady parts, and that's not something anyone wants to see, no matter how fit she is.
