Ask for donations to your favorite one or more charity in lieu of gifts or wedding favors. If you're fortunate enough to have a wedding, give back. It'll feel just as good as saying "I do."
Limit your number of bridesmaids to 3-4 at very most. Nobody wants to be at the end of 10 girls PLUS a terrible view. First-hand experience? My lips are sealed.
Going smaller is undoubtly going to be more intimate. Let's be honest, does one really talk to 500 people on a daily basis? For "$250 a head," I don't blame George Banks for ending up in jail.
It's the cut, stupid. The carat isn't half as important as the cut. So make yourself a diamond expert and do your research before you pop the big question.
It's about the marriage, not the wedding. Kim Kardashian (along with 50% of America) has shown us that an expensive wedding does not a happy marriage make. Spend more time prioritizing what it means to committ yourself to a life together instead of a four hour event.
Walk down the aisle with both your parents. Do you really want to take a page out of the 1930s playbook? My mother plays such an incredible part in my life that I couldn't imagine asking her if she could politely "take her seat in the front."
