Short answer
The fitting records every difference and the pattern encodes them — the deepest reason bespoke fits where nothing else does.
Why it happens
Human asymmetry; no size chart records it.
Why ready-to-wear cannot fix it
Size charts grade uniformly; general asymmetry audit is a personal geometry. A block adjusted in one place pulls in another — which is why the correction must exist in the pattern, not in the fitting-room mirror.
How the house drafts for it
The fitting records every difference and the pattern encodes them — the deepest reason bespoke fits where nothing else does. The correction is recorded in your Fit Passport, so every later commission starts from it automatically.
Where it matters most
This correction carries most for: suit, shirt, trousers, womens suit. It is reviewed at every fitting, in every city, for every garment.
