A Double-duty dress, a terrible tuxedo and a colorful clown costume, the stars are rocking all the wrong trends this week!

Natalie Dormer raised some eyebrows at the premiere of "Hunger Games: Mockingjay Part 1" in London on Monday, donning a black Nicholas Oakwell gown featuring a peek-a-boo bedazzled blue panel and sheer sleeves.

While we applaud her for taking a fashion risk, the actress looks like she layered the black dress over the blue one. She paired her mismatched ensemble with a messy 'do that made her look sloppy next to her glamorous costars. 

Lorde landed on our WTF list this week for wearing this oversized tuxedo on the "Hunger Games" red carpet.

The "Royals" singer definitely didn't look like royalty in those baggy black trousers and extra large jacket. The talented teen needs to step up her style game, but she's definitely earning some points back for her sleek 'do and killer red lip.

Kiernan Shipka missed the mark this week at the Hamilton Behind the Camera Awards on Sunday, sporting a ruffled clown-inspired mini. The frumpy frock not only swallows her petite frame, but it makes her look like she belongs at the circus ... not on the red carpet.
