This outfit is called Emerald Evening. It's sort of a glamorous 1950s style--like the rest of DeeAnna's wardrobe--and it's very lovely. It's green iridescent taffeta, which reflects red--perfect for the holiday season. The feathered headpiece adds a nice touch, too.
Her wig is by Goodreau, and her new eyes are acrylic by Glib (in Iced Tea). You can see more photos on my Flickr photostream or the full shoot in Mobile Me. Also, for the curious, see DeeAnna modeling the same outfit here. Enjoy!
