Short answer
Sleeve shaped at the elbow so the cuff falls square naturally.
Why it happens
Elbow bend angles the forearm away from a straight sleeve.
Why ready-to-wear cannot fix it
Size charts grade uniformly; bent elbows 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
Sleeve shaped at the elbow so the cuff falls square naturally. 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. It is reviewed at every fitting, in every city, for every garment.
