A high-low white nightgown, a black lace bodysuit and a see-through dress over underwear -- stars are rocking all the wrong trends this week!

Kaley Cuoco usually stuns on the red carpet, but the "Big Bang Theory" star landed on our worst dressed list this week for donning a shapeless, sleeveless white frock on the red carpet at A Night At Sardi's in Beverly Hills on Wednesday night. The blonde beauty looks like she's wearing a nightgown that she cut off in the front to show off her shoes! 

Lizzy Caplan raised eyebrows at the same event, donning a lace Houghton jumpsuit that looks like Catwoman got transported into a Edwardian era film. This bizarre ensemble is worse from the back! When the "Masters of Sex" star turned around, photographers got a close-up of the black strip covering her bum!

And, Kim Kardashian caught everyone's attention during an appearance on "Late Night with Seth Meyers"on Tuesday night -- and not in a good way. The reality show star paired her long-sleeved dark green lace outfit with high-waisted black panties, a black bra and strappy gold heels (can you say déjà vu?).

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