I realize its 'your thing' Roy, but I think this photo demonstrates more than ever that trimmer trousers would look more flattering on you.
However, as I don't post pics, feel free to ignore this comment.
I don't 'do' double breasteds myself PoP, and yours is obviously an unconventional version, but I think that high-buttoning four-to-button looks great on you and is an interesting variation that is sadly all too rare these days. I think, Lazenby wore a similar jacket in OHMSS, and I've seen something similar by the ridiculously overpriced Real Stars Are Rare. Was yours custom made or OTP?
As Ian Malcolm says in Jurassic Park, 'Just because we CAN, doesn't mean that we SHOULD!'
It invariably looks fucking shit, even more so by those who really should know better. If you can't be bothered to button your collar buttons or buckle your monk straps then just give up and don't bother at all. It never looks good IMO.
