Color matching In the choice of shirts, you can choose some fresh and elegant warm colors or cool colors. Underwear or skirt should try to choose a solemn and generous dark texture material. Avoid wearing white socks of the same color as shoes or pants. Men's belts, ties and other accessories should not be too fancy. Choose simple, generous and solemn colors, such as black and dark brown. Candidates are not required to wear a tie unless they pay special attention to occasions and etiquette, such as the Ministry of Foreign Affairs.
