’Tis the holiday season and with it comes festive spirit and lots of cocktail parties. And last night at The Apartment by The Line, executive creative director Vanessa Traina cohosted a cheery cocktail party with Dakota Fanning and Gabriela Hearst. But it wasn’t just the actress and designer adding charm and style to the occasion, so were a gaggle of pretty young things including Paravel cofounder Indré Rockefeller, Miroslava Duma, and Natalya Poniatowski. As others like Jessica Joffe and Lauren Remington Platt nibbled on light bites and sipped on bubbly, friends and jewelry designers Jennifer Fisher and Pamela Love caught up and took in the elegant wares. It was an evening of shopping for a cause: Ten percent of the evening’s sales went to Save the Children. Clearly a chic way to get some last-minute gifts and give back.
