The TWOK uniforms are terrible. I don't know why people like them so much. Out of all of the uniforms Trek ever had, they were the uniforms that looked most like a costume/facsimile. Pseudo military is just never a good idea. Because, as I said, it just looks like dress-up. Along those same lines, that ridiculous fruit salad Meyer tried to pull-off with the brass in TUC was just awful. I actually facepalmed when I first saw it, and I was ten.
The pajamas are campy and silly, but it's Star Trek doing it's own thing. It's why they work.
