Purple Michelsons London button-down shirt

A beautiful plum/eggplant button down shirt from Michelsons London. It's listed as a large but for similar to his other shirts that are neck is 16 and sleeve length is 34/35. My partner has started weight lifting and many of his shirts no longer fit through his chest. The shirts are in excellent condition as he always wears an undershirt and is fastidious with his clothing.
