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 the same. 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.

Shirt cuffs should be 1-2 cm longer than 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 be buttoned up.

Single-breasted suit: one-button, button it dignifiedly, and open it up to be chic; two-button suit, if only the top button is buttoned, it is fashionable and orthodox; if only the bottom button is buttoned, it is cool and trendy. If it is fully buttoned, it is rustic, and if it is not buttoned 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 buttons, it is standard to button the top two buttons or only button 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.

8. Pay attention to the maintenance of suits. The way you maintain and store your suit has a great impact on its shape and service life. High-end suits should be hung in a ventilated place and often dried in the sun. Pay attention to insect-proof and moisture-proof. If there are wrinkles, you can hang them in the bathroom after bathing, use steam to unfold the wrinkles, and then hang them in a ventilated place.
