I think every bride goes through this right before her wedding, but I'm second guessing my dress

I can't stop looking at dresses and am forcing myself to not go out and look for samples I can buy (my wedding is now less than 40 days away, so ordering is definitely out of the question). I've also been looking at used sites and am tempted to buy a few dresses that have never been worn... what do you girls think? Part of my problem is my dress hasn't been pressed so I can't get a true feel for what it will actually look like. Plus I never had that OMG feeling. Lastly, I am almost tempted to wear my TTD instead...My dress on the model...[img]
