People attend so many weddings, it's hard to tell them apart. However, everyone that attended our wedding still come up to me to tell me how great our band was, and how wonderful the food was. Those were the things we splurged on. Honestly, the flowers, although beautiful, cost a Fortune and won't be remembered years from now.
Whatever matters to you most should be your bigger expense. For me, I wanted to have a great party after our formal church ceremony. I wanted people to have the time of their lives, and they did. You and your future spouse should discuss what matters most, and then build the rest of the wedding around that.
GOOD LUCK!!!!
