These photos were spied on Facebook and, if I follow correctly, depict a pop-up shop for Hey Gentleman Cafe, an Osaka-based dealer in vintage American clothing. The pop-up was installed in an Isetan department store at a Japanese train station.
HGC’s motto is “Loose Traditional Style,” which is a pretty good one.
Enjoy the photos, and browse more Japanese/American vintage style at HGC’s website. — CC
