Brazilian supermodel Gisele Bundchen is daring to bare again for a new Sonia Rykiel fashion campaign.

Famous for her occasional topless shots, Bundchen has gone make-up free and bottomless for her latest adverts.

The new Juergen Teller pictures were inspired by vintage black and white shots of designer Rykiel herself that the snapper and his stylist found.

In one provocative image, Bundchen poses with only thin fabric covering her genitals.

The 34-year-old mother of two is still pushing the boundaries of fashion - she sported a daring half-shaved hairstyle for Balenciaga's 2014 fall campaign.
