Bones: where to find the blue dress?

Does anyone know where to find the blue sleeveless dress actress Tamara Taylor (Cameron) is wearing in the second half of "The Couple in the Cave" episode (the second episode of this season) of the FOX television series Bones? It's a fitted shift dress, with multiple shades of blue and maybe black, kind of patchwork like, but more streamlined. I can't find a picture online, but if you go to the episode on Hulu, you can get a good look at the 31.16 minute mark. a href="http://www.hulu.com/watch/180752/bones-the-couple-in-the-cave#s-p2-so-i0" rel="nofollow"http://www.hulu.com/watch/180752/bones-t…/a
