Hi All!
Just got back from Filene's Basement. I was worried that it would be insane, but it wasn't--it had really calmed down and was actually enjoyable. I was able to get a fitting room without wait multiple times and while I didn't find anything, I'm glad I went. Of course, there were those who tried on right in the store as well. There were still plenty of dresses left at around 1:30...most size 8-12. Thought I'd give everyone an update...I hate crowds and I thought it was worthwhile just to get an idea of what I like/don't like without the pressure of salespeople!
EDIT: If you go, I suggest bringing a camera--even if you don't want to buy the dress, having the picture of it on you will be great when you go to other bridal stores and want a similar style!
