“Our boy is back!” must Paris be chanting. Indeed, Joseph Altuzarra was born and raised in France, but has shown at New York Fashion Week since his debut. His return, though — both a homecoming and a coming out party — didn’t mark any changes in his collection. After all, the man knows his woman; she’s his alter ego. This season the Altuzarra girl is dressed to the nines in intricate beads, pairs shearling vests with billowy dresses, and throws on a broderie anglaise shirt dress like it’s nothing. Herein lies her power; sexuality is not overt, but covered behind the sheer veil of sophistication.
