Unlike with a regular lounge suit, you will not be able to prevent others from seeing your lining due to the open nature of the cutaway silhouette. This explains why the majority of vintage morning coats has a matching tone-in-tone silk lining that does not necessarily catch the observer’s eye. Bespoke customers sometimes want to make a statement and hence they choose a flashy lining in green, red or purple. Personally, I think it does not look very sophisticated and I advocate against it; the lining will be revealed by the knees, which is not the ideal place to direct an observer’s eyes. More often than not, this kind of garment is offered by second tier Made-to-Measure companies who want to attract the uneducated customer.
Sleeve linings have been traditionally striped or white, however, hardly anyone but you will ever see it and as such it is completely up to your taste.
