There's been a lot of press on how much Chelsea Clinton's wedding is costing and estimates have gone upwards of $3 million! I personally think the wedding will come in around $1.5 to 2 million and most of that is on the infrastructure - tents, lighting, air conditioning, bathrooms, etc...
The most important thing to remember when planning your wedding is to keep to your vision and plan the wedding you want, but don't go into debt!
Don't take out a loan. Don't mortgage your house or let your parents mortgage theirs to pay for the wedding. And don't use your credit cards if you know that you can't pay off the bill at the end of the month.
There are a zillion ways to have the wedding of your dreams on your budget. Just think creatively and don't be afraid to ask your vendors and friends for ideas. Turn to wedding magazines and websites for creative ways to save money.
Never lose sight of the fact that you are marrying the person you love and who you want to spend the rest of your life with. That is what a wedding is all about. The flowers and cake and dress are all extras.
