Three-color principle: When wearing a suit, the color of the whole body should not exceed three colors, including coat, trousers, shirt, tie, shoes and socks.

Principle 2:

Trinity Law: When a man wears a suit on an important occasion, three elements must be the same color. These three elements are shoes, belts and briefcases, and black is the first choice. If you wear a watch with a metal strap, the color of the metal strap should be the same as the color of the glasses frame and belt buckle. If you wear a watch with a leather strap, its color should be the same as that of shoes, belts and briefcases, so that it can be integrated and harmonious.

Principle 3:

Three taboos: First, the trademark on the sleeve must be removed. The first thing after buying a suit is to ask the waiter to help you remove the trademark.

Secondly, it is forbidden to wear a jacket and tie in important foreign-related business contacts. Jackets generally belong to casual wear, and generally speaking, they are not compatible with the formal suit of ties. But there are also some situations that are allowed. First, it is ok to wear a uniform jacket to show formality and unity. Second, some leaders are allowed to appear approachable when participating in internal activities.

thirdly, avoid wearing white socks and nylon socks. When wearing a suit and leather shoes, socks and leather shoes look the best in one color. Never wear light colors or colors, otherwise it will look neither fish nor fowl. In addition, it is better to choose cotton socks or wool socks for socks than nylon stockings. Nylon stockings is not hygroscopic and airtight, and it is easy to produce peculiar smell, which will hinder social interaction.
