Hands up who has no idea what to wear in the morning right now? Well, my hand is right up there with you because I find myself in a sartorial panic from Monday-Sunday as the transitional season holds my wardrobe hostage. What starts out as a balmy September morning ends in a scene from The Day After Tomorrow. Try adding a sleeveless knit to your daily wardrobe for the best of both worlds. Championed by Victoria Beckham, Olivia Palermo and the Olsen twins, it’s chic, cosy and oh so functional.
