The most commonly followed or traditional wedding processional order begins with a mother and ends with the bride.
Check it out:
Officiant: Officiant gets a reverend place in the wedding procession order. After all he/she is the one who is going to announce you as “husband and wife”.
Mother of the bride: Bride’s mother walked in by either the groom or a brother and is the first to walk the aisle. Reaching on the second end of the aisle, mother takes her seat. Which is on the left hand side and first row.
Mother of the Groom: Groom's mother walked in by either the groom or a brother and is the second to walk the aisle. Reaching on the second end of the aisle, mother takes her seat. Which is on the right hand side and first row.
The Groomsmen: The groomsmen enter the area one by one. Or they can also come a bit later hands in hands with the bridesmaids. Both ways are observed.
The Best Man: Now the best man makes his entry. He is supposed to stand by the groom while the proceeding is on. He may also offer his services as a ring bearer on the altar.
The Groom: The groom is the next in order. Normally he walks down the aisle solo.
The Bridesmaids: Next entry is made by bridesmaids or they walk down the isle with the groomsmen.
Maid of Honor: Maid is the one who helps the bride in carrying her dress and taking care of her accessories all the time. While the ceremony is on, she stands by bride’s side to carry her possession like bouquet and sometimes the groom’s ring too.
The flower girl & ring bearer: The flower girl carries a flower basket and sprinkles the fresh petals all around before the arrival of the bride. The ring bearer with her carries the ring and walks down the aisle, he hands over the ring to the best man. Kids task is over here. They may join their parents then. These days cute kids make an impressive entry carrying a creative banner with the words, “here comes the bride” or some other unique and different piece of writing.
Bride with her father: Lastly enters the elegant bride holding hand of her father. Father escorts his daughter to the other end of the aisle to the groom. Father hands the bride to the groom, lifts her veil and offers his love and blessing in the form of a kiss. Leaving her on the altar, he joins her mother.
