my wedding colors include lavender but i need help with the other color in addition to the lavander sooo how did you coordinate the grooms party with the brides party members..can you give me details of your wedding
It's not necessary that he match anyone, at all. Classic black tie w/ tux (and vest, if you choose) would look terrific! Or, if he's not part of the wedding party, a quality suit & tie is a great choice.
I think having him stand out a little more from the Groomsmen would be a great idea - but just make sure that the two options that you are going with won't end up clashing....You two will compliment each other no matter what! After all he is your son! Best wishes!
