When you are the best man, you usually look very formal. Shirts are tied in pants, and belts are definitely necessary. Because the belt will be displayed at a certain angle after the suit is buckled, it is recommended to choose a bright and fashionable belt buckle. If you are thin, you can wear a suit as long as it can bear on your shoulders. Generally, as long as the shoulders can bear it, it looks better.
Shirts can be worn with black, navy and gray suits.
Ties can be matched with dark blue, white, pink, silver gray and other colors.
Shirts can be white, light blue or light pink.
You can also check the website of the suit and see which styles are suitable for you.
Hope to adopt!
