I just looked those up because I was curious. The tassels are kind of out-of-fashion, but I guess if you can balance them with other eccentric details (metal tie clip with an animal head on it, a tweedish cabbie hat, an old-fashioned looking vest, etc.), you might be onto an interesting look. Definitely wear them with some nice broken-in jeans--you know the ones with the selvedge that shows when you fold up the hems? Yeah, now I'm digging it. You just need to totally run with the "sartorial" theme. Like, I'd definitely not wear a suit jacket, but maybe it would be cool just to carry one over your shoulders. You have to look accessorized and layered but not in an artificial way.
From a detached SF onlooker:
You'd be better off picking on a thread started by somebody who deserves it. The OP seems quite nice. This type of query has always popped up and has nothing to do with the decay-of-a-flawed-but-magnificent-civilisation narrative, which has something in it but is horrifyingly mawkish.
I have an idea of it as a sort of menswear Radetzky March in which the establishment of the FNB forum is the Battle of Solferino (which probably makes Manton Emperor Franz Joseph), voxsartoria is Count Chojnicki, and so on.
