Sexy. That’s how Stefano Pilati, the newly appointed head of design at Ermenegildo Zegna, sums up his first collection for the 103-year-old brand. The former creative director of Yves Saint Laurent is launching his Couture Collection, a line of handcrafted suits that features some of the most luxurious wools and cottons. Also premiering this fall is the Personalization Project, a made-to-measure service that allows gents to choose from 150 specialty materials. The limited-edition styles (only 100 get released each season) are finished with monogrammed gold or silver buttons and cuff links. The customer’s name or the city and date of construction are sewn into the selvage. Both collections are available at the Ermenegildo Zegna boutique. 337 N. Rodeo Dr., Beverly Hills, 310-247-8827.
