Short answer
Calf ease added invisibly while keeping the tailored line at the hem.
Why it happens
Calf circumference larger than the tapered leg allows.
Why ready-to-wear cannot fix it
Size charts grade uniformly; prominent calves 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
Calf ease added invisibly while keeping the tailored line at the hem. 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: trousers. It is reviewed at every fitting, in every city, for every garment.
