In Europe a dinner jacket and in Canada and the U.S. a tuxedo:

The dinner jacket consists of a sack coat its reverse or schalfasson trimmed with silk satin, a trouser without turn-ups with a gallon per leg and a smoking chemise together. The typical black-tie jacket is single-breasted, ventless, and black or midnight-blue; usually of wool or a wool–mohair blend. You should wear lace-up shoes if possible patent leather shoe.

Additionally you can wear a same coloured or pike grey vest without a cummerbund (wide breaker strip) and with it a bow. It should fit to the colour of the vest and the cummerbund.

The classical bow tie just suits a classical jacket. The bow aligned in terms of colour to the suitable pocket square (Pochette) should not be missing.

In France and Germany the jacket is called Smoking.
