This has started to leave a bad taste in my mouth...
It feels as though the author is trying to convince us that brand clothing isn't actually overpriced, but simply that much higher quality. I mean sure, they would be of higher quality, but would I still call it a scum? Yes, I probably would. Yet, our protagonist tries one pair of jeans and is so blown away that the price immediately seems reasonable. And that was on the 2nd episode; I thought I'd look past it at the time, but I feel like we're only getting more and more of these moments as the manga progresses.
Even though it was the contrast between the delinquent and the fancy environment that I found to be entertaining when I started this, it increasingly seems as though the protagonist is being presented as someone who needs to be "reformed" to properly appreciate "real", or "superior" fashion. They always talk about how she should see clothing as a way to express herself, yet her liking a jacket that reads "tiger spirit" or with a huge tiger on the back is ridiculous?
I don't know if the author wanted to show some general appreciation towards fashion and different styles, but what I'm getting here is fashion elitism.
