someone asked this a year ago and never got a proper answer, so I’m answering it myself:
People living on a planet called Centrino?
The definition of the girls at St Trinian school, which is not what they say, wore long skirts and school uniforms. I am watching the episode now, and wondered about it too, as they use the word like a commonly known thing. The sort of shepherdess outfit Sandy ends up wearing as a ‘mistress of Centrinia’ or more confusing. There is a Centrinian publishing company of children’s book, but that is even further off of the black stocking risque look that was implied in the show. Can’t find a thing; now Wikipedia when I need it! .
I’m watching that episode now.
People who live to be 100 yrs old plus?
