The background of the wedding theme is blue. What color suit should the groom wear?

First of all, the landlord needs to pay attention to the needs of the occasion. As the best man, you can't steal the groom's thunder, so the color of the suit should be low-key and steady. Needless to say, you can only choose black. I think white goes well with shirts, other colors are not solemn, ties. . . I don't think we should wear this thing now. It's out of fashion. If you really want to bring something, you might as well tie a bow tie, at least in line with this era.
