I would recommend Cad & The Dandy, I have had a number of garments from them: two-piece suit, tweed jacket and three odd-trousers; with another two odd-trousers to follow.
They even did a good job on some alterations for me.
I did try someone above the Cad & The Dandy price bracket, but below Savile Row, at the end of last year. Not the process or final product, someone would expect for the price.
Every tailor in the world, will have at least one unhappy customer....
