The father typically stands on the right side of the bride. This is just custom and not necessarily a rule.
Being that we are in the 21st Century he can do either or he can take them both down the isle. Tradition would have been the REAL mother of the bride, not the step-mother. You discuss it with the father. He should have an input into this matter.
The biological father should give the bride away. If the bride is not close to her biological father for reasons between them then she could choose her stepfather to give her away.
It should be the bride that decides the color of the groom; best man; ushers and father's attire. If the groom, best man and ushers are wearing darker suits then the father should as well. No one should be in complete white other than the bride unless the bride decides she wants to be a little different. Although most whites seem white they are not and the bride should be the focal point and not the father.
A TUXEDO would be best.
Since the father of the bride walks the bride down the aisle, who else would do it?
Both men and women should extend their hand to shake the bride's father's hand and then say, 'Congratulations on your daughter's wedding.' Keep it simple.
In the recent Father of the Bride movie, Steve Martin plays the father. In the original movie, Spencer Tracy was the bride's father.
The wedding surrounds the bride and groom and neither have too many responsibilities with the exception of: * The bride and groom have the first dance together * The bride should dance with her father first, then her father-in-law or any male representing the groom in place of the groom's father. * Mingling with the guests and thanking them for coming.
The bride can do anything she wants as it is her special day and it is fine to have her father on the left and her brother on the right as they walk down the aisle. If you decide to do this then after the minister asks who gives this bride away the father will answer and he will turn to the left to be seated on the bride's side of the church and your brother should walk behind you after this and join your father.
The groom and the bride's fathers can both wear a tux. It would be okay for the groom's father to wear a nice suit because he would not be the one walking the bride down the isle.
First, you should get permission from the bride to be and your brother as to whether you can invite your friends to the wedding and let them know how many of your friends you are inviting. Weddings are extremely expensive and at the reception the food from the caterers is calculated by 'plate settings' which can run from $25 per guest and up. If you have had permission then you would get the invitations from the bride and fill them out and mail them asking the bride for help if you are stuck in filling the invitations out.
