I finally got Keys of Marinus on video today, one of the few surviving Who 
stories I haven't seen in my 15+ years as a Who fan.

I've only watched the first two episodes, so I'll give a better appraisal 
soon, but just a couple of observations about the lovely Barbara. As for 
clothes, she starts off wearing tight stirrup-pants (no good bum shots as 
yet :-( ), flat shoes (no heels :-( ) and a fairly loose roll-necked sweater 
that I find curiously sexy. Later, when she is in her long ancient-Greek 
looking dress in the city of Morphoton there is a point when she is lying 
down that you can see the top of her dress and such is the camera angle you 
can just make out the top of her left breast. And of course, her hair is 
something to behold. As for Susan, she's wearing trousers, shirt and 
cardigan so there's nothing particularly Sadwanky about her in this story.

Being something of a shoe and foot fetishist and talking of shoes before, 
although she didn't wear them AFAIK, I can really see Barbara as a stiletto 
heels woman - black, six-inch, patent leather pumps with black stockings and 
suspenders. I think she probaly enjoys nice lacy lingerie.

Millhouse.
