If people are rude enough to invite themselves, the best answer is, as above, "It's a small wedding with just closest family and friends." If you invite your boss, he/she can kind of symbolically represent the company. But not inviting the boss is not suicide, and there's certainly no reason to invite coworkers with whom you do not socialize outside of work (the ones you are inviting are people who are friends). The one thing I do advise is to keep wedding planning talk to an absolute minimum at work--just keep your personal life separate from your professional life.
