Which ever woman thinks first day of your official life together is worth spending you into debt is not worth having. It is not that day that matters it is everyday after.
I have seen people go 60k in debt for a day and get nothing really in return. If you are super rich fine spend what ever you want for simple folk no need for this craziness. Spending more than a downpayment on a place to live is plain stupid for a few photos,a dress uou will wear only once and to show off to people you rarely even talk to.
