Bella Hadid certainly stood out at the Cannes Film Festival on Wednesday at the screening of La Fille Inconnue (The Unknown Girl) wearing a very revealing red dress that literally dropped jaws.

The 19-year-old model, who is sister of Gigi Hadid, revealed, though, slightly more than she bargained for while walking the red carpet.

As she lifted the gown to climb the steps, she pulled the dress a little too far – revealing a barely-there matching thong underneath.
