and I think the reasn for the switch to trousers is probably to stop the endless arguments.
As anyone who has a teenager. They will tell you
That skirt is too short.
No it isn't miss.
Yes it is
No it isn't
Look, it is.
It is the only skirt I have miss, and I have to ewear it to mt great Aunts funeral this afternoon, she insisted we had to wear skirts.
But you've rolled it up at the waist band.
No I havn't
Yes you have, I can see it.
I have to do that or it will fall down.
Etc etc Ad soul distracting nausiam For ever.
Trousers make it easy. Even they can't say a skirt is a pair of trousers!
