I worked in a men's shop in the nineties. Mostly our stuff was pretty good, but there were exceptions. Chief among these was the abhorrent black blazer. Just like our navy blazers, brass
buttons and all, only black. Especially awful was the 6x1 double breasted version...unforgivable. I hated them then, and my mind could not be changed, until...

I came across an
exquisitely made, early 1960s vintage three button blazer, in black flannel. I could feel an old hatred welling up inside me, but this jacket surpassed all that. It confounded me, because as much as I felt I ought to hate it, I actually had to have it. Call it fate.

What really sold me was the open patch breast pocket. It's a detail I find absolutely
irresistible in a casual jacket

The buttons are silver, which is probably kind of cheesy. I might swap them out for braided leather, maybe, I don't know. In any case, I think this jacket worked pretty well against an outfit comprised almost entirely of blue, in this case
dark jeans and a university striped oxford.
It's a conundrum, really, this black blazer. Two days ago, I tried it out with grey flannels and a white shirt with pink stripes. But it was all wrong, reminded me why I once found the black blazer repugnant. That day, I immediately swapped it for my classic navy blazer, and all was right with the world. The today I tried it with jeans and it was just the thing, which is funny, because jeans and sports jackets often work quite well together, but if you ask me, nothing looks worse than a navy blazer and jeans. I don't know, too dorky or something.
And speaking of dark blue jeans...

I like my jeans dark, stiff and old fashioned of cut. I do not like to
wear jeans for a year or more without washing them in order to preserve them, because that's just filthy. Enter Woolite Extra Dark Care. I ran the
Wranglers though the wash, alone, turned inside out, in cold water, with Woolite, then hung them to dry. The results: jeans that are both dark and clean. Go figure.
p.s. watch for this enigma of a jacket with tan slacks and a cream cable knit sweater. That might be just the ticket, too. We'll see.
