Steve, thank you for the detailed explanation!

Burberry products (and several rather close knockoffs) are fairly common in mega-metro Chicago, as to be expected with this size population.

Interesting to know, no male kilts or trews in the catalogue, though ladies' kilted skirts are in internet "images."

About 25 years ago, a Polish manufacturer made trenchcoats (rather nice material and construction) with a similar / slightly different tartan (thread count / pattern) lining; they were colloquially known as "Burberr-skis" and prolific-ish in this area, sold in independent men's stores.
