Yes, that was Matt Damon sitting in the audience at Naeem Khan on Tuesday night, and no, he was not there to choose a dress for when he will undoubtedly win a 2014 Golden Globe for his upcoming turn in the HBO biopic “Behind the Candelabra.” Damon, who has been spotted with his wife around New York this week, was in attendance to support his friend Khan. Truth be told, Khan needed little supporting for his show of cohesive and stunning red carpet-ready gowns. His combination of workmanship, eye for detail, and use of diaphanous chiffons and silks resulted in one of the most sophisticated collections of the week. The sparse deep color choices helped his crystal-encrusted details sparkle. Black and navy gave way to peacock blue as he drew from inspirations as varied as the Byzantine Empire to illustrations of the 1920s.
