I grew up with Gerry Anderson's shows from the early 1960s - I always wanted to be Joe 90 and get things downloaded into my brain (still do) and also think UFO is the best GA show. Dark themes with a cool look (the theme music is great too).
Now back to the point... In the UFO books, yes, there are books, you learn that the purple wigs are in fact anti-static devices! No idea about the miniskirts and knee-high boots though.
