Pink satin, see-through sequins and nautical rope -- stars are rocking all the wrong trends this week!
There's no telling what wacky wardrobe she'll wear on any given day, and Lady Gaga decided to "turn back time" in New York City on Monday.
The Mother Monster donned a long pink stain robe and a big black curly wig as she imitated Cher's look from back in the day during a surprise appearance with Tony Bennett at the Frank Sinatra School of the Arts.
Sorry, Gaga, this look should have stayed in the past!
Mariah Carey turned heads on the red carpet at Clear Channel Media's event in Paris on Tuesday, rocking a sheer, sequined plunging black gown with a black bra underneath.
The singer seems to be paying homage to Rihanna's racy CFDA dress, but the busted front, fish tailed skirt and simple fabric looks like a bad drag costume.
And, Kim Kardashian made quite a statement during the MailOnline's VIP party at the Cannes Lions 2014 Festival on Wednesday, donning an incredibly skintight white rope Balmain maxi dress, featuring gold rings and a zipped back.
While this dress shows off the reality star's killer curves, it looks incredibly uncomfortable. And with every single piece of rope going in several directions, we're not sure where to look first.
But these ladies weren't alone -- see more of this week's worst dressed stars in the gallery above!
