It is ok to wear a suit under normal circumstances. The black one is safer and won't cause a big problem. Shirts are mainly white or light, and ties can be blue. With black leather shoes, never wear white socks.

A suit is a necessary equipment for men. Even if time is too late, you can rent or borrow one, and prepare a suitable suit in the future.

If a friend's wedding is very particular, you can also rent a black morning coat with a bow tie and vest or a dress tie vest, which is very particular. The bride and groom's wedding car is generally the focus of the wedding car. Both guests and photographers will pay great attention to this car, and the driver will certainly attract everyone's attention. A well-dressed dressing gown will add a lot of color to the wedding.

Finally, I wish your friend a happy wedding.
