Executive chef whites, a traditional white suit, and a white tie are the most common wedding outfits, but you can also wear a formal white dress, as well as white sneakers, and black trousers.
For a more subdued look, you could also go for a white blazer, or a tie with a red trim.
If you’re looking for something a little more casual, try a white shirt with a black tie, or black pants and a black blazer.
