@Brian1946 Wow, I see it in your link, but it doesn’t show up for me when I follow Jeruba’s link. Weird.
I’m pretty sure that at least for most people, wearing a particular tartan isn’t necessarily taken as a statement, even by Scots who are into tartans, unless they have a reason to think the wearer is making a statement by it. On the other hand, Nicola Sturgeon has made a statement by wearing a homeless Tartan in the past, about which there are a LARGE number of articles , so she must be aware people are over-analyzing her mask choices.
There are SO many articles about her wearing the first tartan mask with the homeless tartan, that I didn’t find any commenting about her choice of a different tartan mask, even in the articles which show her wearing a different tartan.
