Best Man

Whom to Choose: A brother or the best friend who won’t party too hard after the rehearsal dinner — you do want him to make it to the ceremony, after all. In some parts of the country, it’s customary for the groom to choose his father.

Job Description: Takes care of all bachelor events and provides support to the groom. Keeps track of wedding rings even if there is a ring bearer (you don’t want to assign that task to a four-year-old). Kicks off the toasts at the rehearsal dinner.

Caveat: Picking someone who gets along with the bride is a plus.
