Lottie Moss made her catwalk debut in the Sonia Rykiel AW15 show this afternoon, proving that some things (like, say, modelling ability) just run in the family. Kate's 17-year-old half-sister wore a brocade velvet playsuit and walked alongside Olympia Campbell, Keith Richards' daughter Ella Richards and SS15 campaign stars Elizabeth and Georgia May Jagger.

For AW15, the brand transformed its Paris boutique into a Left Bank literary cafe and bibliophile's wet dream, with stacked floor-to-ceiling bookshelves and library texts. "There is even erotic literature in the changing rooms, a place of self-discovery where the error, as Sonia Rykiel once observed, offers 'the one true dialogue'," the show notes declared. "This self-knowledge and self-regard distinguishes the Sonia Rykiel woman, who is, among other things, an intellectual being."

The show marks Moss's first ever runway show after only just shooting her debut fashion editorial for the Girls Rule issue of Dazed last February. Since then, she's turned Calvin Klein campaign girl for a limited-edition line with Mytheresa.com, landed the AW14 campaign for Red Valentino and even nabbed a spot on the Dazed 100 list.  

Expect to see a lot more of Ms Moss in the next few seasons.
