Susan Kelley, creator of this blog about Kate Middleton and her outfits, writes that her topic is “not trivial, far from it.” She argues that the Duchess of Cambridge’s influence on the culture and economics of fashion is tremendous. But Kelley also says that her subject is “loads and loads of fun.” The site features timely updates on Kate’s doings and what she wore while doing them, e-commerce links that let you wear what she wears and a profusion of photos of the stylish, gracious royal hobnobbing with admiring commoners.
