The number of bridesmaids usually depends on the formality of your wedding, with a dozen being the maximum for any wedding. Girls between 8 and 16 are considered to be junior bridesmaids. Junior bridesmaids are not expected to help with details as much as bridesmaids. Bridesmaids help take care of details for the bride such as running errands, and making table decorations or favors. Bridesmaids usually join the maid of honor in hosting a bridal shower.
Bridesmaids attend pre-wedding parties.
Bridesmaids attend the rehearsal and the rehearsal dinner. They stand near the bride during the ceremony. They are in formal photographs of the bridal party. If travel expenses are involved, they pay their own cost involved in getting to the wedding and staying in town during the celebration. Although bridesmaids may attend several pre-wedding parties, only one shower gift and one wedding gift are to be expected.
