A stupid dresscode question:
The official word of the Orient Express goes:
You can never be overdressed on the Venice Simplon-Orient-Express. The historic decor of the train and its atmosphere encourages everyone to dress to suit the occasion. Dinner provides you with a marvellous opportunity to recreate the style and glamour of a bygone age. For evening dinner many travellers will wear black tie or evening dress.
Is white tie/tailcoat overdressed?
