Dave ohhhhhhh no, you must do things properly my friend, invitations are very important, this is not an ordinary wedding, this is a Filipino wedding, Filipino weddings are a great occasion, you must plan plan plan.
You must get down to the printers with your girl and sort out what theme you will have for your civil wedding, what will be your theme colors Gina and I had orange and cream as our theme, then you must decide, what your
Give away
will be, lots of people tend to go for a little married couple on a house, or a wedding cake with couple give away, these are little tokens of your marriage that the guests will want to keep, at the end of the ceremony and socializing, your guests will want to come out and get theres.
If you do want to see a wedding in the Philippines, and the procedure, take a look at mine, I have nothing to hide, here it is at.

Its a rough guide to give you some idea of what to expect, as Ian Busby has said, the only thing that is not a changing constant, is the number of guests that you will inherit at your wedding, unless of course as a British friend of mine lamented on last year when we were in BOB'S CAFE "I do hope that girl is an orphan" then you will not have as many guests.
