NOTE 2/22/09: Thank's to Lauren, who informed us that both links did not work anymore, we have a new link up.
The link Lauren gave us, has the exact dress, basically, only in a lighter color. It's Dress 2 above. Thank's Lauren!
Note: We have found out this was from the Grand Ole Opray, and the images we had found, were from the autograph signings afterwards. (We're pretty sure.)
