We always love seeing "Mad Men" stars on red carpets because it's so strange to see them out of their retro garments, especially the ladies (for the dudes, a suit is a suit). As if to set herself as far apart from her character as possible, January Jones went with a very modern, graphic Roksanda Illincic at this week's season premiere. The "Mad Men" aesthetic has definitely rubbed off more on Kiernan Shipka, who wore a demure, but still vaguely futuristic Nina Ricci number at the same event.
This week also saw a parade of more Nicolas Ghesquiere for Louis Vuitton -- this time on longtime Ghesquiere muses Jennifer Connelly and Chloe Sevigny. We're kind of obsessed.
