Ushers are usually brothers, relatives or best friends of the groom. In inviting people to serve as ushers, make sure that they are aware of the expenses involved. While it is not necessary to have an equal number if ushers and bridesmaids, it does balance nicely if they walk in pairs in either the processional or recessional. Groomsmen usually help the best man plan the bachelor party for the groom. Groomsmen attend pre-wedding parties.
Groomsmen attend the rehearsal and the rehearsal dinner.
The main Job of the usher is to seat guest. They should arrive at the ceremony site at least one hour in advance and should have a clear instructions on the seating plan. In Jewish services, the seating is opposite, with the bride's family on the right. Female guest are escorted by having the usher offer his right arm to her. Her date or spouse walks behind.
