Short answer
Inner-thigh ease re-drafted and wear-resistant cloth recommended at the fitting.
Why it happens
Inner-thigh contact plus coarse cloth.
Why ready-to-wear cannot fix it
Size charts grade uniformly; thigh rubbing 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
Inner-thigh ease re-drafted and wear-resistant cloth recommended at the fitting. 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.
