This lovely doll was a UFDC exclusive from 2008. Surprise Engagement uses the Daphne sculpt with dark brown hair and painted blue eyes. She is limited to only 210 dolls, and can be quite difficult to find.
I believe she was part of a design competition, and no one knew which doll was chosen until the doll was opened at the luncheon. Her gown is a taupe satin with velvet print, with a mint oversized bow on the back, and she's just lovely!
