0125_wtf_launch Checker-inspired couture, sheer paneling, an ill-fitting silk jumpsuit -- stars are rocking all the wrong trends this week!

Lady Gaga continues to take the top spot on our toodrab list. She was photographed visiting a museum in Paris on Monday, sporting a checker board-printed jumpsuit with shoulder pads and sky high black patent platform shoes. Mother Monster topped off the look with a mop of long grey braids.

Is this really acceptable during Paris Fashion Week!? We don't think so!

Gaga wasn't the only star to commit a crime of fashion.

Paris Hilton nearly showed off her lady bits on the red carpet at a pre-Grammy event on Thursday night in a super sheer Antonio Berardi gown. The strategically-placed cutouts made it clear that Paris wasn't wearing any underwear.

And, Kim Kardashian showed off her cleavage at the Stephane Rolland in Paris, stepping out in an all-silver ensemble with a plunging neckline.

So plunging, in fact, that she accidentally revealed her nude bra, which was clearly supposed to remain hidden behind the silver top.

But they weren't alone -- see more of this week's worst dressed stars in the gallery above!
