In London I didn't find most SR tailors accommodating to my figure or what I wanted, with the exception of John Kent, who is great but on the expensive side (or at par with the rest of the SR folks, really). Ultimately, I chose Dan Macangus from Macangus and Wainwright, who is very technical and detail oriented, open minded and studious. He modified a lot of his "ways" to accomodate my figure (most particularly the inner waist darts on the coat, and the shape of the seat of the trousers, as well as the pleats). Dan in my main guy

In Madrid I work with Joaquin Fernandez Prats whom I find equally skilled and accommodating.

Here in Southern Italy I'm still exploring, but overall I find the Neapolitan and Sicilian tailors to have a very strong understanding of "non standard" body figures.

Finally, Frank Shattuck, while very controversial in every single forum I've been to, has a pretty strong eye for big/non-standard figures.
