Your wedding is one of the happiest days of your life, and hopefully, the main reason for that is because it's an opportunity to stand up in front of everyone you love and publicly make a commitment to the one person you adore most in all the world.
However, it's also a big deal because it's all about you (hopefully, you two, plural). As you can tell from the fact that everyone from your grandmother to your uncle to your former roommate's cousin's cat has an opinion about how you're doing it - and whatever you do, at least half of them are convinced you are doing it wrong - your wedding is an event for which you will be judged.
While obviously everyone's unsolicited opinions aren't helpful, the fact is that how you envisage the day does tell you something about yourself. More importantly, in this context, it tells you something about the side of yourself that most appealed to the guy (or gal!) standing beside you at the altar, under the chuppah, or perhaps just on the beach in bare feet.
Perhaps you plan to be the ultimate bridezilla, with eight bridesmaids and matching groomsmen and a wedding that costs 50K. Maybe you dream of getting all your friends to cosplay cast members of your favorite sci-fi franchise. Perhaps you dream of eloping to Vegas for a quick, trashy, cheap wedding that inconveniences nobody. Either way, it'll tell you a little about why your boo said yes - or perhaps, asked the question to which you said yes - in the first place. So let's find out!
