We predicted the wet-look leggings trend would be big but we weren't totally convinced women across the world would don skin-tight leather and PVC for everything from red-carpet events to their weekly food shop. Well they did. Everyone from the Olsen twins to Angelina Jolie (not forgetting the UK's club kids and high fashionistas) seems to have a pair. We think the reason behind the en-masse wet-look obsession is their sheer versatility and instant wow-factor. Throw them on with a fabulously detailed tunic top and tailored jacket for a Christmas party look that right up-to-date or a simple sweater dress with boots for an off-duty look that will give you style credentials of Kate Moss proportions. Or something! But have you joined the wet-look brigade?
