I had a terrible experience with MTM Orazio, I wonder how much it depends on the person taking the measurements vs. the people making the suit. But based on my experience I have trouble trusting them with any order. On the other hand I have heard many great things about Orazio from members here and friends in Europe...I'm curious what he means by "inside, fit, etc."
I like Simon Crompton and read his blog, but I take some of what he says with a pinch of salt. I can imagine him getting a bespoke jacket made identically to an Attolini jacket inside and being convinced that it has these 'superior' construction features even when it doesn't.
As for fit - that depends on the individual and his body. How do your Attolini garments fit? My RTW Attolini couldn't possibly fit better - they are supremely comfortable and there are no unsightly pulls or areas which are too loose or too tight (unlike with many of Simon's bespoke jackets).
Have you considered MTM Orazio Luciano? I'm especially impressed by what the Parisian Jean Manuel Moreau does with them. Simon actually featured them recently so you will have seen them.
I have seen Jean Manuel Moreau on instagram... looks great. I thought he was a tailor but seems like they "just" have a shop and sell MTM suits ?
