Interesting. In the 'real life' pics he looks dreadful.
I only know about Jason J because JFM used to plug him in return for his plugging of JFM.
So, by the definition of dandyism that we've been referring to so far, JJ is not a Dandy. And that suggests that there is no such thing as a Dandy and only a dandy look, which I think is the argument put forward by Sauce and P. Smith and others.
This is in opposition to Shooman's view I believe. So, come in Shooey. It's your turn again to come up with a workable definition of the being Dandy for 2021.
