Petra Nemcova had a few hits and a few misses at the 69th annual Cannes Film Festival.

The model took a big fashion risk and donned a sheer jumpsuit at the Chopard party sans bra. It's unclear whether she intended to show off her bare chest or if it was an unfortunate wardrobe malfunction.

She also took an embarrassing tumble on the red carpet at the premiere of the Spanish film "Juliet."

Nemcova looked stunning a day later in a metallic dress with pleating detail but that didn't stop the 36-year-old from tripping over the number in front of the cameras.

She quickly recovered and returned to posing with a steely gaze.

Between the tumble and the sheer top, Nemcova still had a great time at Cannes.

She wrote on Instagram, "@Chopard night in #Cannes is always so incredibly special. So excited for the #ChopardParty with theme #WILD!"
