For a non-denominational ceremony, a secular ceremony, or a non-traditional ceremony, you can either borrow one of these traditions or make up your own rules. In all honesty you can usually arrange your processional however you choose. You can arrange it any way you’d like but to make it easier on yourself have either a coordinator or a friend with a written list helping to line up the bridal party and telling each person when to go. Make sure they stand just beyond where the guests can see them. They should also remind each person to smile when they’re walking down the aisle and make sure to leave a pause before the bride enters.
