I have some old bespoke shirts from 20+ years ago but my neck has grown fatter and I can't do up the top button anymore. Some of the cuffs are also fraying. I lost contact with the original shirtmaker many years ago, his phone is not connected and he is no longer at his old address. If I can find a new bespoke shirtmaker, is it possible for the collars to be replaced in order to accommodate my now-fatter neck and can the fraying cuffs be replaced (provided I can find fabric that matches the body of the shirt, or otherwise, a fabric which contrasts with the body of the shirt in a pleasing way)?
Cuffs surely. Collar, I would guess not, but if you love the shirts, I suppose its worth finding a tailor and asking what he can do.
