Adrianna Papell - little black dress:  $3 @ Winners (RSP:  $200+)

It's hard to see the details, but there are pleats at the front and back.  Out of her other dresses, this one looks the most similar:

The pleats intersect, unlike the other one above.  I'm also sure there used to be a belt that went with the dress, but it's long gone.

Still, the quality and fit are amazing!  I needed a classy black dress, and I probably couldn't have found a better one.  

It was cheap because the zipper was broken, but that's a pretty easy fix.
