This is the kind of dress I wish could still be worn without the fear of being 'costumey'. It's a picture taken from an odd site that I can't quite puzzle out. Click on the picture if you'd like to take a stab at it.
The other thing that keeps me from wearing a dress like this is the realization that, if I did, I would walk around with my arms held out like that ALL THE TIME. Which would make it hard for me to work my iPod. So that can't happen.
It's hard to tell, but this dress does have a collar. I know that comes as a big surprise to you all.
