Morphology
The meaning is directly derivable from combining 'dinner' (evening meal) with 'jacket' (a short coat): it denotes a jacket worn for dinner or evening occasions. This noun+noun compositional pattern is common cross-linguistically and in English, so a B1 learner who knows both constituents would likely infer the semiformal evening-wear sense.
Etymology
Dinner jacket comes from the simple idea of a dinner jacket, a jacket worn to 'dinner' at evening events where people wanted something less formal. In the 1800s men began wearing a short dark jacket instead of a very formal coat for evening meals, so today dinner jacket means a less formal black or dark jacket for evening dress.
