I wouldn't wear the cutoffs because they look sloppy. As a former software engineer, I think I'd likely wear a khaki skirt with a nice button down Oxford blouse and some sort of Wellington boot. In the winter I'd recommend a nice Stewart plaid skirt. I've even been known to wear my university tie with a four in hand knot. Not the most feminine look, but Anglophilia is fashionable - as a British friend told me, she went up at least three social classes in the US just for her accent. B^)
