The Attolini jacket is fine. Orgetorix is the master of fashion--we all know that. But the coat doesn't fit. It just doesn't, at least to my eye. It looks too snug, only a bit, but still. A pity. He looked, in my opinion, better in an Oxxford suit that caught my eye long ago because it fit like it was made for him. This coat does not. Feel free to say I'm a dork, but he should see whether his tailor can let it out just a bit.
Now, on to the William Gates jacket...
Bill Gates is known for many--well, maybe just a few--things. Being well dressed is not on the list. The jacket he is wearing in the offered picture is ill-fitting, and that's being charitable. Just because he's rich doesn't mean that he knows how to dress. He looks, looked, way better in an impossible to screw up OCBD and shetland sweater. Warren Buffett, who is tight with Bill and even richer, also does not know how to dress. Neither Gates nor Buffett puts a premium on fashion, certainly less than the average pro athlete whom they could buy and sell a thousand or more times over. Yes, I would have jumped all over that jacket as fast as the OP. Is it a better jacket than Orgetorix's Attonlini that belonged to who knows who? I say no.
Which is to say, Orgetorix and Bill Gates would both look better in less expensive fare that fit them better. And so they really are equals among men. At least, in my book.
