Cannes Film Festival 2017 Worst Dressed: Pamela Anderson, Jessica Chastain and more

The annual Cannes Film Festival is known for its glamorous red carpet fashion, but not every look is a total hit!

This year's 10-day movie festival featured some gorgeous dresses (Elle Fanning was the ultimate style queen) but there were also some stars who stepped out in some horrific styles.

Jessica Chastain has been on nearly every Cannes red carpet, but we didn't love all of her outfits. The actress arrived at the screening of "The Meyerowitz Stories" in a gaudy green ensemble that was a hybrid between a coat and gown. We were just left totally confused ...

Victoria's Secret model Sara Sampaio was also another fashion offender -- the brunette beauty hit the red carpet in a see-through ensemble while wearing only a white lace thong underneath. The sheer number was a little too scandalous for Cannes.

And believe it or not, Pamela Anderson also made this list. The former "Baywatch" babe arrived at the screening of "120 Beats Per Minute" wearing a demure black gown that didn't flatter her famous figure at all. Come on, Pam!

Check out the slideshow above for some of the worst looks at this year's Cannes Film Festival.
