Perhaps a showrunner read by post (I did ask them to, after all) and decided to dress Cam differently, but in a completely ridiculous manner.
Here's the background: A body is discovered in a cornfield, and Cam arrives to examine the body. She's dressed in a shift dress and a blazer:
Cam: Oooh. Dead things.
Booth: Hey, Cam. Why are you all dressed up?
Cam: Oh, I have a date later.
WHAT? WHAT? WHAT? WHAT?
I now consider myself officially slapped in the face by all parties associated with the making of Bones. Ouch.
And also, WHAT?!
