OK, believe it or not, my wedding gown in hanging in our guest bedroom as I type this!  That's right, I've already got my gown in hand.  We haven't registered yet, sent out save-the-dates, or booked our florist, but I have a gown.  
So let's take a look at a couple of gown shopping myths.  
#1: You need to order your gown at least 6 months in advance.  While I can't say that this is 
completely false, it's definitely an exageration.  I was under this impression, and clearly, it was not necessary.  I started looking pretty much as soon as I knew the "when" and "where" of the wedding, around the beginning of March.  I went to a LOT of stores, and tried on probably close to 50 gowns.  I know that I am an indecisive shopper, and I knew that simply deciding on which dress would take some time, which it did.  It took a good month of shopping to feel like I was comfortable with my decision.  But once I placed the order, which was early April, it took about a month from the time I placed my order until the dress arrived at the shop.  Obviously, it will vary from designer to designer, but you don't need to feel panicked when you hear/read from "reputable" sources that if you haven't ordered your dress a year in advance, your ruined.
Myth #2: You need to order your dress too big so that it can be altered to fit you perfectly.  I think that this myth is the result of bridal salons that have in-house alterations and can get more money out of you by getting you to spend unnecessary amounts on excessive alterations.  I had someone in the biz tell me this.  When I got measured, they told me that I was one size on the top and a larger size on the bottom (I do not think this is unusual for most women), so I should order the larger size.  I said that based on the cut of the dress, I thought the smaller size would work.  I asked them to consult with the designer.  The designer agreed, the smaller size was ordered, and today, when I tried on the gown, it fit (nearly) like a glove.  Yes, I will probably get some minor alterations done to make it fit perfectly, but I could easily wear it as it is now.  And the shop that I purchased from actually doesn't do in-house alterations, so they didn't really have anything to gain by putting me in a dress that was too big.  Plus, now I can use whomever I want to do the alterations, and hopefully get them done without too much expense.
I have so many pictures of my gown purchasing trips, but I can't show them to you yet because I can't risk JT seeing them on the blog!  So you'll all just have to wait patiently until after the wedding for my recap.
