Bear in mind that a "dinner jacket" is NOT the same as a sport coat. Rather, it's correctly worn only with black formal "slacks" (?) that have black satin inserts, a pleated (formal) shirt, a bow tie, and a vest or cummerbund. A "tuxedo" strictly means a specific style of dinner jacket first worn at a very exclusive private country club in New York named The Tuxedo Club
, though many people wrongly use the term to refer to formal outfits with other styles of dinner jackets.
