Kate Moss' sister, Lottie, is the face of Calvin Klein's new ad campaign.

The 16 year old - who was signed to Kate's agency Storm Models earlier this year - models the iconic denim brand's latest collection in collaboration with the luxury online fashion store Mytheresa.

The collection, called The Re-issue Project, is a capsule of denim pieces from the 90s - including tapered boyfriend jeans, high-waisted skinnies and 'cK' sweatshirts - which will be available tomorrow (15.07.14) exclusively on mytheresa.com, reports The Daily Telegraph.

Lottie's debut as the face of Calvin Klein comes 21 years after her 40-year-old sister starred in her first ad campaign for the jeans company along with actor Mark Wahlberg in 1993.

The shots were taken by photographer Michael Avedon who described working with the pretty blonde as ''wonderful''.

He said: ''Lottie truly represents the essence of the Calvin Klein girl. Intriguing innocence with utter beauty - it was wonderful to photograph this beautiful young lady!''

Meanwhile, the luxury online store are thrilled to have teamed up with the iconic brand.

Justin O'Shea, buying director for Mytheresa.com, said: ''For me there is one brand which epitomises clean American sportswear and denim - Calvin Klein Jeans. We at Mytheresa.com have seen a huge resurgence in fashion towards the aesthetic which Calvin Klein Jeans pioneered, which led to us collaborating with the brand.''

Lottie - who shares a father with her older sister - started out modelling for Dazed & Confused magazine as well as Teen Vogue and has previously spoken of her desire to become a fashion journalist.
