I really really appreciate everyone's responses, and no, I did not think that this was going to be cut and dry. Some of the comments are really helpful though.
Well, here's an update. We went back to the store yesterday with a different aunt and my grandma. They didn't like the straight one at all, so that was a downer. Then they went searching for more, so I tried on every style of dress I believe there is,

Well, now I've seen many types and really liked another, but I am heeding some advice from this board to continue looking.
The question now is, instead of which dress (not that they're out of the question yet) but I am now starting a poll on which style of dress looks best on me. I like some and not others, but those who saw me try them on, again, had differing opinions. I'm curious about what the DISers think...
I really appreciate all of your comments and opinions...and no, I don't get offended, hey, you may see something I don't!!!
So enjoy looking at some more pics and PLEASE VOTE!!!
