Valérie Trierweiler, France’s repudiated ex-First Girlfriend, showed us all how you can win street cred in egalitarian Socialist France while attending the Christian Dior show at Paris Fashion Week. Simple, really: get there (and leave afterwards) on the Métro. Smile for every single camera trained on you, be it professional TV crews or a smartphone. Look smashing. Say little. Do not even try to occupy that (virtually) empty middle first-row seat, where the country’s First Lady normally holds court next to Anna Wintour. Wash, rinse, repeat at the Saint Laurent show.
