Back in the day, you had one best man. That was it. He held the rings, gave a toast, and threw the bachelor party. One dude. One job.
But times have changed. You probably have a best friend from college, a brother you actually like, and a cousin who’s been your rock since you were seven. Why would you choose between them? You don’t have to.
Modern weddings are all about your rules. If you want three best men, you get three. Just know that “best” becomes a very flexible term.
