A slick tuxedo-inspired silhouette can instantly add structure, sex appeal, and an empowered sense of glamour to any red-carpet ensemble. At last night's amfAR New York gala, we spotted five star-studded examples of the menswear-friendly style. Model Joan Smalls suited up in a lapel-infused floor-length gown, complete with a peplum pop at the waist; singer Janelle Monáe opted for a more traditional tuxedo blazer over a black wide-leg jumpsuit; and model Liya Kebede stunned in a sportier version of the tailored trend by wearing slouchy tuxedo pants with a silky blouse. Whether you take a more literal approach to the trademark tuxedo staples (read: blazers, lapels, pantsuits) or interpret the look with a more feminine twist (think soft dress shirts and peplum details), we think it provides a superchic finish.
