It may be winter in the real world, but in the fashion world, we are already moving on to spring and summer! And there’s no better way to get a sneak peak into what our wardrobe will be when the weather gets warmer than looking at the latest ad campaigns, in which actresses and models collide. Lauren Hutton graces the latest campaign for Bottega Veneta, looking every inch the iconic supermodel/actress whilst carrying the brand's newest bag called the City Knot. Michelle Williams and Jennifer Connelly front the latest Louis Vuitton Series 6 campaign, while Chloë Sevigny is in J.W.Anderson and Vittoria Ceretti is the model of the moment. Here is a look at some of the best new spring/summer campaigns out there.
