Gotta be a shorty. That’s why he doesn’t like jeans. It’s OK flashy, turnups are in fashion now.
He strikes me as the sort of (short) chap who would have his tailor run up trousers that didn’t require turning up. As for ‘De Nimes’ being the Devil’s Cloth – there were many London District regiments who held that belief and forbade anyone from wearing it. However, I doubt the Flashmeister was ever tall enough for the Guards 😀
