Bridesman

It was then the custom, to prevent any coarse pleasantry which old times perhaps admitted, that the key of the nuptial chamber should be entrusted to the bridesman.

It was customary, in those days, for the bride's-man and maiden, and a few select friends, to visit the newly married couple after they had retired to rest […].

According to him, on the following Thursday, the bridesmen, numbering “six, eight, even ten or more,” rode on horseback with four wagons to get the bride.

She might be renting a tux, however, as she is willing to have a bridesman.
