Take this suede leather sportscoat for instance:While at a glance it looks like something you might expect to find from the 1970s (especially with that orangish-brown color), this sportscoat is actually from the 1940s, perhaps a little earlier.
The devil is in the details, such as the belted back with two small pleats above it and buttons:
And the 1940s-style tag as well as the silver/gray rayon lining:
Or the Art Deco plastic buttons:
Happily, the Fall/Winter 1944-'45 copy of the Sears, Roebuck catalog
shows an incredibly similar suede leather jacket (sans belted back):
Now, what to wear with such an unusual vintage jacket?
How about something casual like a flannel button-down shirt,
vintage Stratoliner fedora, jeans and vintage sunglasses?
My first vintage leather jacket.
