double breasted Prince Charley

[MacLowlife]

Drummer Boy, there are a handful of "frequently appearing " doublets with a double breasted front- some might argue the name implies two layers of cloth. The jacket we usually call a Montrose is one example- search for Montrose and you can see several nice ones. Your tailor or retailer might call it by a different name, though.

I think the OP was talking about actually buttoning his PC with an overlap, which a tailor would probably not recommend. (The back is as wide as the front and there is no way to overlap the fabric back there.)

As for the DB jacket CMcG shows us, I suspect it may not have any flaps in the back. Glen's link above takes you to a recent DB jacket thread over in the General Kilt section, but no rear views of those jackets appear there, either, as he says. AFAIK, the metallic epaulets are the personal choice of the wearer...
