A dated pantsuit, a Beetlejuice inspired getup and a sloppy mismatched mess of a look -- the stars were rocking all the wrong trends this week!

Rose McGowan looked nearly unrecognizable at GQ's "Men of the Year" bash in Hollywood. The shiny white pantsuit looked about two sizes two big on the "Charmed" actress, and the sneakers just brought her ensemble to a whole new tacky level.

Elle Macpherson normally has flawless style, but the model looked more like Beetlejuice in her black and white pinstriped pants and baggy black blouse at the Chrome Hearts celebration in Miami. While the 50-year-old's stunning, nonetheless, we think she should throw these pants in her never-ever-wearing-again pile. It's OK Elle, we all make mistakes from time to time.

And Scout Willis -- who in no way is known for her style -- went for another unusual look at the Paper magazine bash during Art Basel in Miami. The gold satin pants, black oversized blazer with the black bandeau bra seems more like three different outfits mashed up into one sad excuse for a red carpet look. Scout should start taking some style tips from big sis Rumer Willis, she at least gets it right half of the time.
