Not tabulating the misc. will cause anyone to go bankrupt, and not just in a wedding. Mr. M and I married 18 years ago and total cost from gown to appetizers to the victorian b&b was right at $450. I have to say that my best friend got hitched two weeks later and her gown alone was over $2000 and she was ticked because mine was waaay nicer. It's ludicrous to spend what amounts to a new car or a hefty downpayment on a house on a couple hours of one's life. If a bride needs a spreadsheet, the groom may want to think twice what her future drain on the family income may be.
Well, the two of us are neck and neck in salary so the drain works on both of us equally :)
