It's critical that setting your budget be the first step in planning your wedding. It might not be the most fun part of the process, but it’s a task that really needs to be completed first because it sets the rest of your wedding planning process into motion. The last thing you want is to fall in love with a venue, vendor, dress, etc. and realize it’s completely out of range. So sit down with your parents or other potential contributors to come up with a total budget, and then divide it up by vendor or service accordingly.
