This one was too plain

This one had too much...stuff

This one was too expensive (I know, I know...I shouldn't have tried it on in the first place)

But this one was just right:

This last one is my favorite so far...it's a sample gown so it's a really really good deal. If I wasn't just starting my shopping this weekend I totally would have bought it. But I really want to keep trying on dresses because, well, this will be the one time in my life that I get to do this!
Anyone else who's gone dress shopping: how long did it take for you to find your gown? How many dresses did you try on / how many stores did you go to? After you found your dress, did you keep shopping anyways just to be sure?
