My advice – establish a budget.
People tell me all the time they don’t know what they want to spend. When I start throwing around figures, though, it becomes apparent what they don’t want to spend! Having an idea of cost will help you manage the wedding with ease. You may not be able to afford your dream everything, but you can decide what’s important to you and splurge on that aspect. For everything else, search for great alternatives to fit within your budget.
