The following is an actual transcript from a conversation I had last night via Twitter. (Names have been changed to protect the innocent.) I've posted it here because I thought brides-to-be might find it instructive and/or reassuring.
friend: Nervous about my wedding dress. Why did I have to find the perfect $250 vintage dress today, huh?
me: @friend did you try it on?
friend: @me Nooooooooooo. But now I want to go back. This is so pathetic. I was NOT looking for a dress.
me: @friend you're not pathetic. this is normal. go try it on and get it out of your system. chances are it won't even fit.
friend: @me That is such good advice. You're a good advice giver.
Be prepared for wedding dress ambivalence to hit 3-4 months before the big day. I'm not saying you have to go try on other dresses, but it might help you love the one you've got.
Or you might buy a new one like I did. Oopsy.
