Someone posted this today on Ivy Style's Facebook page. It's a jacket from Sears' "Traditional Collection," which the owner dates from the 1960s. The lapels appear to bear that out; they're a little narrow for my taste. But check out the other details: 3/2 roll, swelled edges, and natural shoulders, which the owner reports as an ultra-tradly 19".
It's hard to believe that stuff like this was once so widely available; Ivy style obviously spread beyond the northeast and the rarefied confines of purveyors like Brooks Brothers and J. Press, to middle America and even to middle-class outlets like Sears. SEARS! Amazing. (My recent post on long-wing "gunboats" also showed a pair from Sears that I found on eBay.)
