Striped culottes, granny panties and a frumpy printed frock -- stars are rocking all the wrong trends this week!

On the heels of her flapper fashion disaster at the Met Gala, Lupita Nyong'o decided to buck the trends again and go with something bold, patterned and totally different from the sophisticated gowns she wore during award season.  

The "12 Years a Slave" star walked the red carpet at the 2014 CFDA Fashion Awards on Monday, rocking an unflattering striped culottes and top combo.

While we applaud the actress' risk-taking stance on style, we're missing those classic gowns from the Oscars and SAG Awards.

Chrissy Teigen raised some eyebrows at the 2014 Gordan Parks Foundation Awards Dinner & Auction in New York City on Tuesday, sporting granny panties under a messy sequined sheer gown. 

Sorry, Mrs. John Legend -- sheer doesn't always mean sexy! 

And, Kate Walsh missed the mark in a strapless Naeem Khan black and white printed gown at the 2014 CMT Awards on Wednesday.

The fussy pattern and the ultra-conservative heels just don't  flatter the 46-year-old's slim frame.

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