Hopefully cash to pay for the wedding
If his bride to be has no problem wearing his mother's wedding ring then it is fine to use the wedding ring for his future bride. However, if the son has sisters then he should get permission from his sisters as generally the jewelry of the mother goes to the daughters and they may want to keep it as a keepsake.
No, the father of the bride has no obligation to give his daughter anything on her wedding day as he is paying for most of the wedding which can be very expensive. However, some fathers may give some extra money to their daughter depending on the father and it is the mother that may give a piece of jewelry that either belonged to her or her mother.
the punishment you can give a bride on her wedding is to ruin her dress or mess up the wedding
It is not written in stone that a mother has to give her daughter a personal gift, but some mothers may have a lovely piece of jewelry that they have had or the piece was given to the mother by her mother and she may want to pass it onto her daughter. The mother and father of bride do give a wedding gift either the day of the wedding at home or, leave the wedding gift at the reception.
The father of the bride and groom can give the wedding gift to them the day of the wedding at home or, they can leave the gift on the gift table at the wedding reception. However, if it is of cash value it is better to give the bride and groom the money before the wedding.
Generally the mother of the bride and the groom's mother get their corsages when the bride's; maid of honor; bridesmaids flowers are delivered to the bride's parent's home, but if the bride would like to give her mother a bouquet of flowers personally from her then it should be done in private (at home) or, if you want to give the bouquet of flowers to the mother then also include the future mother-in-law or it is poor etiquette and there could be some hurt feelings by the mother-in-law.
yes
Since you are the boyfriend of the mother of the bride you should go out shopping with your mate and it's etiquette that the gift come from both of you or, she could help you out choosing something for her daughter.
Traditionally, the Maid of Honor or bridesmaids give a shower for the bride. Tradition does not necessarily apply, however. Anyone who wants to can host a wedding shower.
Speech of mother good
Often the groom will give a toast to his bride and also the Best Man. At the request of a parent it is quite acceptable for a father or mother to give a toast as well. There are no strict rules any long to what one wishes to do at their own wedding.
