You just hit 1000 posts Shell!
My advice is to try on only a few each time you visit a store as it can be overwhelming. I tried on 10 in one store and I couldn't really remember the first ones, so I ahd to try them on again.
I found my dress in the very first store I went to, but I tried on dresses in other places, just to be sure.
Be sure to find something you are comfortable in and you still feel like yourself, remember you have to sit stand, dance...
Good luck and let us know how it went!
