This has been a fascinating (and somewhat dizzying!) thread - a lot to take in and catch up on after being gone all day.
From what I'm gleaning here, we are all products of our experiences - everything we have ever seen, heard, felt, read, or touched - and no two people will ever feel 100% exactly the same way about anything, especially something with a history as long and iconic as Burberry tartan.
This is how I see it:
Subject A lived an isolated life as a child. She dreamed of leaving the same four walls behind and seeing new things. She devoured books and movies about travel and adventure, and her library had a particularly wonderful selection on spy thrillers, mysteries, comics, and sci fi. She became hooked on James Bond, Get Smart, noir films, Bladerunner, Dr. Who, X-Men, The Matrix, etc. She never encountered a real-life person in Burberry until later in life, but she always carried that image of Super Cool Action Adventurers in Trench Coats in her mind. Burberry, being the original trench coat brand, became extra cool by association. Now that she can afford it, she jumps at the chance to buy a Burberry of her very own.
Subject B grew up well-off yet sometimes felt repressed. Her parents worked a lot and always seemed more interested in buying the latest status pieces and "keeping up with the Joneses." Her parents loved to certain brands with recognizable logos, and Burberry was one of them. She violently rejected her parents' way of life when she turned 18. She moved to a big city and reveled in local businesses, special restaurants that didn't exist anywhere else in the world, unique treasures at thrift stores, biographies, and books on philosophy. She loves the idea of celebrating individuality rather than searching for connection through iconic pieces. She has seen people and other characters in trench coats, but those stories held no particular emotional connection for her. Now, when she needs a coat, she doesn't even consider a Burberry coat that her mother might have suggested. Instead, she scours Etsy for a designer willing to make a coat with custom details just for her.
And of course there are millions of "subjects," and the range of experiences is unfathomable. I'm sure many people don't feel an emotional pull of any kind in regards to Burberry. Some might just like the design of one particular Burberry coat and that is that. Many don't know any fashion history and don't care. Many people are revolted by logos of any kind. "Horses for courses," as Angie has been saying.
It shouldn't be viewed as wrong to like or dislike anything, and I don't think it's fair to judge others for their likes, either. A good friend of ours was a victim of a hate crime when he was young... to this day, he is very biased against the race of those who attacked him. In a perfect world, no one would be biased, but we can't blame our friend for being a product of his experience.
Yikes, I have typed a novel here... to wrap up the thought... can't we all just get along?? We can never know the entirety of any attraction. There is not enough data to "judge" whether an attraction is moral or justified or whatnot - not that most of us could or would change what clothes we like even if a crowd of our peers deemed it wrong.
