I believe this to be a version of American jackass: I had on 501's -- which I bought too large because I thought they'd shrink but they didn't. I had on Church's plain bluchers. Dark grey J. Press wool socks, white t-shirt old with hang-dog collar seam, and a blue pinpoint oxford cloth Brooks shirt with windsor collar (old version, made in USA). I wore the collar open and the shirt untucked. Sleeves rolled up a few times, maybe three. I like this look. It might be my new one.
