I've seen quite a few posts where people refer to the Tuxedo, a tail less dinner jacket as a Tux. This is incorrect- the correct term is Tuck.
The Tuxedo jacket was introduced in the United States in 1886 at a a party at the Tuxedo Club in Tuxedo Park, NY. First worn by the country club founder's son Griwald Lorrilard who cut the tails off his dinner jacket the tailless jacket quickly became the club's informal uniform.
I do much of my shooting in Tuxedo Park which along with Newport Rhode Island was one of the guilded age's residential areas. (Pierre Lorillard actually sold the original Breakers, a wooden structure, to Vanderbuilt. After it burned to the ground the Breaker Mansion that currently stands in its place was built).
For those interested in history there is a great book on how radar was developed in a house in Tuxedo Park during WWII that allowed landing and spotting of aircraft as well as research on the atomic bomb. I'm a bit of a historian on the guilded age and Tuxedo Park and would be pleased to answer any questions people may have, but even if you have no interest whatsoever, there is no word Tux. It's either Tuxedo or Tuck.
