Over the past few years I've had in my possession suits from nearly every top tailor (bespoke and ready-to-wear) in the world although a few have evaded me (notably Gianni Campagna, Knize, and Caraceni.) I've formed some opinions through my examination of each suit and by comparing them to each other. However I can't exactly tear them apart and look inside. Nor have I had the privilege of visiting the Flagship stores and asking salesmen who know about the exact tailoring processes. So I'm wondering if Mr. Naturlaut, Mr. Thracozaag and anyone else who can be of assistance would be willing to offer their knowledge and opinions. How would you rate the following makers on the quality of their tailoring? I mean purely on the basis of the amount of handwork and the precision and aesthetics of the stitching - not taking into account the different philosophies of styling that each maker prescribes to. What makes one suit a "13 hour," another an "18 hour," another a "25 hour," etc? I know I am asking a lot but any details you may be able to recall would be very interesting.
