Thank you, gentlemen. I credit at least part of my success in dressing well to the advice (sometimes strongly stated) from these fora - occasionally, when one bangs one's head against the wall enough times, either the wall moves, or good sense enters the skull. I leave it to your judgment as to which has occurred .
As for Anderson & Sheppard, I am sure that they'd be more interested in my modeling skills were I a paying client - as it is, I've not the cash nor the time in the UK to have something made by them - yet.
Tibor, as someone with more years of experience in wearing hats, I will tell you that, as you age, either your skull with get a bit larger, or your hats will shrink - slightly oversized is not such a bad thing.
