Kate Moss for Longchamp

Looking at last week’s photos of Kate Moss honeymooning on a yacht in St Tropez, it would be easy to believe she lives a charmed existence. But you don’t get to be one of the world’s most successful supermodels (according to Forbes she made £8.2 million in 2010), without some business acumen.

Moss has four perfumes to her name, a role as a beauty ambassador for Rimmel London, still consults for Topshop and owns a global property portfolio. And, of course, she’s a mother to eight-year-old daughter Lila (and now wife to Kills guitarist Jamie Hince). Yet somehow, she’s still found time for another new project: her fourth handbag range for French luxury label, Longchamp.

The newest collection of Kate Moss for Longchamp, which launches in store this Thursday (12 August), is possibly her best yet. A combined design effort by Kate and Longchamp’s artistic director, Sophie Delafontaine, it focuses on the iconic Gloucester duffle bag from one of her previous collections. “It is a real staple of my wardrobe,” Kate told Stylist. The bag has been reworked in suede, comes in three sizes (from small to a holdall) and is available in new colours, khaki and burgundy. Kate explains that the khaki design is a particular favourite: “I wear the colour a lot, because I think it goes very well with denim. For me, khaki is a basic colour – a kind of new neutral.”

The design also cleverly incorporates the snakeskin trend. “I was inspired by a vintage miniskirt of mine,” she explains, “which has a mix of brown and black shades. I thought that was different and more interesting than the usual snakeskin.” With Kate’s fashion credentials, we’ll take one of each please.
