Calvin Klein has been blasted on social media for its latest underwear campaign.

The most recent Instagram advert features an ‘up-skirt’ photograph of a model looking down into the camera with the caption: “I flash in #mycalvins”.

The photo was posted with the comment: “Take a peek: @karate_katiaphotographed by @harleyweir for the Spring 2016 campaign. #mycalvins”

The racy image, though, has been branded creepy, sexist and ‘fodder for paedophiles’.

Although actress and model Klara Kristin is in her twenties, followers argued that the ad make her look a lot younger.
