The tailored suit option is a win-win situation for grooms and their attendants. Every member of the wedding party can be measured for a suit that will fit each person perfectly. In addition, the guys are sure to wear suits again in the future with much more regularity than your average tux.
If the cost of a new suit is too much for all your groomsmen, just give them a dress code to abide by. Whether you select navy, gray or black, chances are your attendants have something that will do already hanging in their closets. Plus, coordinating neckties and silk handkerchiefs make excellent groomsmen gifts!
