Michelle Obama’s unique, down-to-earth yet fabulous approach to fashion has shoe lovers around the world drooling. Last week, she stepped out in a pair of sweet Lanvin sneakers similar to the one shown at right. (Ms. Obama’s pair, which she wore while volunteering at a food bank in Washington, DC, were grey with a pink toe and slightly less extravagant laces.) While the fashion critics are raving, others have voiced criticism regarding the appropriateness of wearing such expensive shoes to a charity event (a pair of sneaks from the French designer Lanvin usually run over $500). Regardless of how you feel about celebrities and conspicuous wealth, you have to admit that Ms. O is lookin’ good these days. She’s spawned sites dedicated to following the First Lady’s fashion, including The Cut from the New York Times and Mrs. O, a blog.
