Changing into a different dress from the wedding gown

I don't like that in the episodes of My Fair Wedding that David has the brides change into an alternate albeit lovely gown from their wedding gown for the duration of the wedding. Maybe I am old-fashioned, but to me wearing the wedding gown is all part of being the bride. All the other ladies there are also in special lovely dresses/gowns and in my opinion it doesn't make the bride seem as special.
