Dinner Jacket

A dinner jacket — known in American English as a tuxedo — is the defining garment of black tie dress code. Typically in black or midnight blue, it features silk-faced lapels (shawl or peak), no exterior pockets, and a single button. It is worn with matching dress trousers bearing a silk braid stripe.

Midnight blue reads blacker than black under artificial light. This is not a styling trick — it is an optical truth that the best tailors have known for over a century.
