I think it's more about what Kylie says (preaches, more like) and what she does. In "How we Met" video, and a few other times, she says she never drinks or have one night stands. The drinking has been disproven, but the whole German nightclub project was built around a one night stand concept. Even if it was just a story, it doesn't mesh with her judgey mcjudgerson attitude towards such things.
Also, I personally hate cliche dressing. Like when I see tourists around in their huge sun hats and lemon print or everything , it's just so cringe. I also don't know any Florentine women going around in rouje vintage style dresses, and jodphurs are left for the actual riding. Her outfits going to the post office and to Guido's office (skirt, boots, wool coat) were more within the norm. Anyone notice the wife in Kylie's lunch video? Rich AF and from a noble line...in jeans and a tee.
Of course she can wear whatever she wants, but it all seems such a put on for the cameras and yeah, clichè. If she had met a Milanese businessman, I think she'd be wearing all black, fur coats and more logo influencer style looks "because that's how people in Milan dress." (I forgot about her tacky Gucci blinged out rich kid street style she picked up while in Rome). If she had met a Venetian artist she'd be in various gondoliere style striped tees with blown glass jewelry. A stereotypical view for her fans who most definitely hold sterotypical ideas about Italy and Italians.
