It's a very ladylike way to add sparkle to your outfit: show it on a sharp collar. Found in the Fall '11 collections from Givenchy, Miu Miu, and Valentino, the look is surprising versatile and definitely statement-making. Emma Watson paired the collar with a sequin jacket in her most recent editorial for i-D mag, and Hailee Steinfeld looked adorable in a beaded sheath at a Miu Miu party. While a pearl-embellished top from Valentino is available now ($1,090), we expect it will be a short matter of time before this trend pops up in more affordable versions. Wear it on its own, with the blouse tucked into slim trousers or a pencil skirt for a polished look. For a more offbeat approach (the way we would do it!), layer it under a crew-neck sweater or sweatshirt, skinny jeans, and oxfords for a back-to-school look that is totally cute and unexpected.
