A group of ultrarich San Francisco socialites, each with a carbon footprint the size of a small African country, gathered at the home of Larry Ellison's wife Melanie Ellison. The good cause: to promote author Sloan Barnett's book Everything Goes with Green — which just happens to suggest everyone buy her husband Roger Barnett's Shaklee "green" cleaning products. But the conflict of interest wasn't nearly as chatworthy as the conflict of couture!Quelle horreur: Both Barnett and Marissa Mayer, Google's vice president for cupcake-recipe spreadsheets, wore the same blue Oscar de la Renta dress with a green-leaf pattern along the hem! Also, it seems that arm-candy real-estate manager Zack Bogue is trying to tear Valleywag editor Owen Thomas's affections away from stubblicious Flickr developer Cal Henderson by sporting some ursine facial fur. Though my guess is he was just too lazy to shave — that the top button and not the middle button is buttoned on his pinstriped jacket says "sloppy." (Photos by Drew Altizer)
