The actor and U.N. Messenger of Peace arrived at the event looking every bit the leading man in a sleek black suit, which he accented with a tasteful navy and gray striped tie and a United Nations dove pin affixed to his jacket’s left lapel. Angela Weiss/AFP/Getty Also in attendance: environmentalist and actress Shailene Woodley, who rocked an earthy look in varying shades of blue at the U.N. The 24-year-old Divergent star donned a set of dark wash skinny jeans, a plunging teal blouse with bright orange and yellow accents, and an oversize denim jacket with the collar partially popped.
