As asked in title.
I know traditionally it goes:
Chief Bridesmaid | Grooms Father | Brides Mother | Groom | Bride | Brides Father | Grooms Mother | Best Man
For us this changed a little because my Mum is doing the Dad duties (giving me away, doing a speech) because my 'father' is non existent.
I'm being very silly and stressing over having an odd number of people on the table but can't think of anyone else who could be on there.
