That's true. It should be "easy" to measure how many people go to her shows. Kim on the other hand has Skims and sells a lot. So how many people buy vs go to concerts would be interesting to compare.
I was thinking also the media attention a show brings (esp with her ticketing chaos) but that is prob more name recognition vs face. The Kanye connection must have also made Kim’s face more well known I guess. Would be very surprised if Skims has a large Asian or African market.
According to this https://holler.country/news/general/taylor-swift-concert-tour-2023-tickets-and-dates Taylor will have 38 concerts in this tour. Let's say she gets in every concert 125k people. That's almost 5 million people in her tour. If we double it, that would be 10M.
