Many brides and grooms buy gifts for each of their attendants. Traditionally, they are presented to the recipients at the wedding rehearsal, on the morning of the wedding, or when the speeches are made during the reception. 
Some brides and grooms choose chose an identical item for each attendant, while others choose a personal gift for each bridesmaid and groomsman. A possible gift for each attendant might be an accessory to complete his/her wedding attire.
For bridesmaids, a jewellery set with matching necklace and earrings is a popular choice, while for the groomsmen, a dapper silk vest to slip under the tuxedo, or handsome cufflinks are both suitable options. Perhaps the gift can also be personalized with the date of the wedding or the recipient's initials.
