It's by Cesare Palermo, the former right hand man of Vincenzo Attolini when they were both at Rubinacci. I have some photos of his workshop, and have been meaning to write an article for StyleForum's blog (actually have a couple article I owe to Fok), but have been too busy lately do a proper piece. The stuff I saw in his workshop, however, was really remarkable. If I were to be able to go to Naples on a more consistent basis, he'd be the first tailor I'd go to.
And no, he doesn't travel, or have a website. I honestly don't even know if he has a telephone.
As for inlandisland's question of whether those colors are true to life, I don't know. It's been too long for me to remember that specific jacket in such detail. I like how the color is in the photo, however, and am considering getting something like it for myself.
