You know the drill - a celeb wears something and suddenly, it's bound to be a trend. Much like Nicole Richie and her denim jacket, Kate Bosworth recently donned a denim vest and suddenly fashionistas everywhere are rushing out to purchase the item. I'm not sure how I feel about the trend - I suppose if it's done right, a la Bosworth (see below), it's doable. But I think it's a trend that will a) only work on very petite frames and b) has to be done via a worn in rocker-chic vest, not one of those tight fitted ones from Forever21. 

That said, if you can find a worn in one at your local Goodwill, do it up Bosworth style with a miniskirt, oversized grey tee, and colorful scarf. Movie star sunnies optional.
