There are no innocents. There are, however, different degrees of responsibility.

Director Thomas J. Wright in the Millennium 3-11 Commentary
Frank Black's wardrobe on Millennium was fascinating to me because of how atypical some of the choices and combinations were on camera. There were various crew changes on the production, so I wasn't sure who actually did the costume design. The answer surprised me, I can tell you that much.

I thought it was interesting that Chris Carter credited someone else (especially for him), because to my - admittedly untrained - eye, it seemed to me like that person must have had very limited influence over the initial selections, and from what he says later it does sound like she had very little influence in general. It's not even that I disliked some of the pieces, it's that I didn't think they looked great together on camera, which is a completely different thing. The idea of "simple and basic" didn't exactly translate for me (as someone who was an adult in 1999) either, but I do like to see Frank in green, I must admit. I did try to watch with an eye toward Chris Carter claiming the character changed and I think I know some of what he meant. Frank starts to wear more varied colours like red, plaids with lighter colours, and at one point he even wears black to bed (instead of thin, see-through grey) and...I liked it. I like the idea of character development and growth. I liked the idea that Frank changes when he moves between different environments and different parts of his life. I thought it made more sense than how limited his wardrobe was (especially after just having arrived from Virginia) at the beginning of the show, when he was still happily married.
How did Lance Henriksen get cast in Millennium, despite how much he never wanted to do tv?
Chris Carter: "Lance Henriksen really was the first and last choice." Lance Henriksen, basically: My agent tricked me into reading it. David Nutter: You'll never believe this one weird trick.
Millennium Director of Photography Robert McLachlan on the use of lighting, from the DVD bonus feature:
The low lighting used in Millennium and The X-Files was an atypical approach to take for TV shows in the 90s.
