"Spoilers!", as 'River Song' would say. If you continue reading this post and you don't know the identity of the Doctor's wife and her connection to the Time Lord and his traveling Companions, then best to come back when you do. Otherwise, feel free to enjoy this fantastic costume worn by Alex Kingston as the enigmatic and mischievous character, plus more outfits and props on display at the Doctor Who Experience in Cardiff Bay, Wales on December 9, 2013.
You can also see another original River Song costume from Doctor Who (from the fifth season 'The Time of Angels' episode) from a previous visit to the Doctor Who exhibit here at Hollywood Movie Costumes and Props.
In subsequent episodes of the show, we learn that aside from being the future spouse of the Doctor and an archeology Professor, River Song is actually the grown-up child of the Doctor's married Companions 'Amy Pond' and 'Rory Williams'. Born 'Melody Pond' she was conceived in the T.A.R.D.I.S. and so possessed similar genetic traits and regenerative abilities as the Gallifreyan Time Lords.
If you like this selection of outfits and props, be sure to also check out additional Doctor Who Companion costumes on display, and more besides.
