I can see the "help" as being more along the lines of "For Zen's sake! Would someone get that barbarian American properly attired?"
Which I guess goes to show what I think of as offensive, in terms of dress. It's not offensive until it's wrong, and even then, most of what is offensive is the poor aesthetic rather than something really offensive. If I'm going to dress in a cultural outfit, I want it to look right and look good, not like a drunk toddler trying on clothes.
Which is why you get the equivalent of a tailor and a gentleman's gentleman. You can grab something labeled "3-piece suit" off the rack at JC Penny but that does not mean that you will know how to put it on and move around in it properly. The tailors at Franco's (a high-end shop in Richmond) could make anything fit me properly, but the salesmen, after huddling and tut-tutting, offered t buy back the suit saying I would never be able to pull off anything more than a sports coat.
The Japanese friends (and their friends) who tried to put my kimono to rights did not see my errors as offensive so much as the opportunity to show off to each other their complete knowledge of both the donning/wearing of the outfit and the cultural history of the kimono. Now if only even three of them had agreed with each other.
As for kilts? My limited experience is that it is combination of the opportunity for Scots to get the tourist drunk enough to agree to try it and make fun of the tourist, getting the tourist even drunker so they can make more fun of the tourist, and perhaps most importantly of all the opportunity to have (at long last) a reason for getting drunk that did not end in the letter "Y".
stay safe.
