Suits are becoming more and more popular among people because of their beautiful design, simple and smooth lines, strong three-dimensional effect and wide adaptability. It has become almost universal clothing, suitable for men, women, old and young. The suit is 70% in the making and 30% in the wear. The selection and matching of suits is very particular. When choosing a suit, you must consider color, size, price, fabric and workmanship, and you must not ignore the shape, lines and proportions. A suit does not necessarily have to be made of high-end materials, but it must be cut to fit and neat and straight. Choose a monochromatic suit with darker, calmer colors, no obvious patterns, but higher-end fabrics. It is suitable for a wide range of occasions, has a long wearing time, and has a high utilization rate. The following etiquette principles should be followed when wearing a suit: (1) The color of the upper and lower parts of the suit should be consistent. In terms of matching, two of the suits, shirts, and ties should be in plain colors. (2) Leather shoes must be worn when wearing a suit. Casual shoes, cloth shoes and travel shoes are not suitable. (3) The color of the shirt worn with the suit should be coordinated with the color of the suit and cannot be the same color. White shirts look great with suits of any color. Men should not wear brightly colored plaid or patterned shirts on formal occasions. The shirt cuffs should be 1-2 cm longer than the suit cuffs. You must wear a tie when wearing a suit on formal and solemn occasions, but not necessarily on other occasions. The shirt collar buttons must be fastened when wearing a tie, and the shirt collar buttons should be unbuttoned when not wearing a tie. (4) Suit buttons can be divided into single row and double row, and the button tying method should be particular: double-breasted suits should have all buttons fastened. Single-breasted suit: One-button, buttoned up dignifiedly, open and unrestrained; two-buttoned, only buttoned with the top button, it is fashionable and orthodox, only buttoned with the bottom button, it is bold and trendy, and buttoned with all buttons, it is rustic, both If it is not fastened open, it is chic and handsome. If it is fully buttoned or only the second button is buttoned, it does not meet the standards. If it is three buttoned, it is standard if it is buttoned with the top two buttons or only the middle button. (5) It is not advisable to put too many things in the jacket pockets and trouser pockets of the suit. Don't wear too much underwear when wearing a suit. It's best to wear only one shirt in spring and autumn. Don't wear a cotton sweater under a shirt in winter. You can wear a woolen sweater outside the shirt. Wearing too much bulk will ruin the overall beauty of the suit. (6) The color and pattern of the tie should be coordinated with the suit. When wearing a tie, the length of the tie should be enough to touch the belt buckle, and the tie clip should be worn between the fourth and fifth buttons of the shirt. (7) The trademark label on the cuffs of a suit should be removed, otherwise it will not comply with the dress code of suits and will make people laugh in elegant occasions.
