The word "shirt" can mean a button-down American shirt, an open-collar Aloha shirt, a Cuban shirt with impressive pockets, and so on. There are also Japanese-style shirts.
When I look at the "Walbusch" shirt from this perspective, I think it is very European. The poplin fabric, the unstitched front, the square-cut hem.... And above all, the royal blue color and the slightly larger collar of the shark collar with a core. I think this is a detail that cannot be found in any other land. Don't you smell the atmosphere of the rough hems worn in movies, or worn with brown jackets?
In today's Internet-enabled society, there is a mood of soft flashi-core rather than crispy adhesive-core. The imbalance between casual and dress. Why don't you enjoy this kind of shirt now more than ever?
