The clothes also had a retro patina, but if some of the skirtsuits looked stuck in the 1940s, other numbers were pleasingly old-school. The sweetheart-neck, patchwork floral day dresses that Lindsey Wixson and Marihenny Rivera Pasible modeled would be an easy sell with the street style set—why haven’t those peacocks discovered Posen yet? After dark, a silk crepe evening jumpsuit and a tulle bustier worn with flared wide-leg satin pants moved the proceedings forward a few decades to the Studio 54 era. Most of the designer’s attention, though, was focused on gowns, and one thing he’s learned over the years is that timeless plays on the red carpet. So does color—the color story here was gorgeous. You could picture either Gwyneth Paltrow or Grace Kelly nabbing the best-dressed prize in Posen’s jade green duchesse satin and tulle strapless ball gown.
