I and all of my tech people wear clean blacks for all ticketed performances, whether in the booth, backstage or deck.
If we have rented out the
house and the show has their own LD, sound people and
stage manager, or it is an non-ticket show then techs are in blacks and I am in black shirt and shoes and khaki trousers.
If it is a CCSO, Corpus Christi Symphony Orchestra performance, then all techs in blacks and me in black suit with a tie, usually red because I hate ties.
If, for some reason, techs show up in black shirts (T type) that has lettering on it, I use the ever present and multi-functional black gaffer's tape to cover the lettering.
At no time and no way are shorts ever worn, even though we are on an island and that is what most of the students live in constantly, along with their flip-flops (which used to be called thongs, btw) which are also not worn on any call.
When you are called to work, you dress for work, otherwise I couldn't care less what you wear.
