BAGGING CARLA: Speaking of the first lady, who gave a royal flush of fashion credits to Dior last week during her London sojourn, Tommy Hilfiger is the next brand hoping to benefit from her fashion touch. A limited edition tote signed by Carla Bruni-Sarkozy is to be put up for auction April 21 at Hilfiger's Parisian flagship on Rue du Faubourg Saint-Honoré. The item is one of four remaining bags from the sold-out line launched last fall to benefit the Breast Health Institute. A gaggle of fashion bloggers, including Cory Kennedy, will be among around 60 high-profile guests who will be invited to bid. Bruni-Sarkozy has also been approached to squeeze an appearance into her schedule. For faraway fans, two signed bags will also be sold via online auctions on tommy.com and elle.fr in the run-up to the event, while Hilfiger's Parisian flagship will host a silent auction open to the general public during the three weeks leading up to the event.
DOUBLE BOOKED: Dakota Johnson — spawn of Melanie Griffith and Don Johnson and newcomer to the Manhattan social scene — painted the town red on Thursday night. Decked out in a scarlet Moschino cocktail number, the 18-year-old aspiring model and actress (she just signed with IMG) stopped by Saks Fifth Avenue for a W magazine-sponsored preview of Moschino's fall line. Next, Johnson headed downtown to Paris Commune, where she joined a Zac Posen-clad Eva Amurri at her fete benefiting the UNA-USA's HERO initiative. A gaggle of young thespians like Taylor Momsen, Mamie Gummer and James Snyder (who headlines the new Broadway production of "Cry Baby") rubbed elbows with the hostess' mom and step-dad (Susan Sarandon and Tim Robbins). Silent auction lots included photos by Sarandon and Robbins, a dinner and wine tasting at Daniel and fashion looks from Alberta Ferretti, among others. Amurri's charity (for which the starlet is a Goodwill Ambassador) supports children in HIV/AIDS communities in Sub-Saharan Africa.
