It's not just the many Olympic sporting events that kept our attention in London. The star-studded spectators, including Kate Middleton, Kate Moss, Michelle Obama, and Naomi Campbell brought their styling A-game to the Games, too. There's a bevy of sporty daytime looks to sift through — the duchess's blue printed Whistles dress rounded out the closing ceremony fun — and more formal evening ensembles, like Kate Moss's gold-embossed vintage tunic dress and Gucci T-strap sandals at Naomi's charity dinner to kick it up a notch. Plus, we have to hand it to the FLOTUS. She really knows how to dress with a respectful nod to our country's colors without veering into over-the-top Fourth of July Americana territory. To see Michelle's outfits in action, as well as the Kates going head-to-head, keep reading — starting with Kate Middleton's closing ceremony outfit.
