Kendall Jenner ups the glamour in an extreme plunging gown with a short hemline and a sweeping train as she parties in Cannes

She was the toast of the town at the Magnum beach party earlier in the day, looking the picture of class in an elegant jumpsuit.

But Kendall Jenner certainly saved her best look until last, emerging later on Thursday evening in a gorgeous patterned gown with a plunging neckline as she kept the party going at the evening event during the 69th annual Cannes Film Festival.

The 20-year-old showed off some serious skin in the daring dress, which was cut to under the bust and featured a thigh-skimming hemline.

Kendall's striking dress featured a colourful overlay in flattering shades of orange, purple and brown.

The asymmetric material was gathered at the waist and flowed behind her as she made her grand arrival, flanked by her momager Kris Jenner.

The Keeping Up With The Kardashians beauty displayed her long and lean legs in the dress, setting off her glamorous attire with simple strappy heels.

Earlier in the day, the model was channeling something between retro Parisian chic, old Hollywood and nautical inspirations in a jumpsuit and cat eye sunglasses.

The brunette was flanked by her mother Kris, 60, who was less subtle in her style choice and reflected the sea vibes at the Magnum beach party with vigour in a striped ensemble.
