Does the groom dress just like his groomsmen?

Usually, the groom is different, in some way from the other men in his party. He may wear a different tuxedo, or just a different vest than the ushers. Usually, the ushers’ vests will match the bridesmaids’ dresses. The groom’s vest is usually a neutral colour, such as black, white, or silver, to complement the bride’s dress.
