You can wear a bow tie or a tie, but be careful that the color of the tie or bow tie is not too bright, so as not to cast a shadow on the groom.
Best man clothing requirements
First, dress formally and don't be too maverick. But we should also consider the theme of the whole wedding and try to dress up in line with the whole atmosphere. What does the best man wear at the wedding? If you are not sure, a white shirt or striped shirt and formal pants can never be wrong.
Second, don't neglect accessories. Accessories are also very important, and details determine success or failure. If you think the tie is too formal, you can also choose a bow tie, which is both appropriate and fashionable.
Third, highlight the taste. In this grand ceremony, the taste of the best man will also represent the newcomer, so you can't make yourself look too tacky.
