I used to fly for a private operator, midsize bizjet. We got new suits every year (& always from NEXT). We could pick the design we wanted as long as it was dark blue or black in colour & it was the same design. Also always get two or three pairs of trousers with one jacket because the trousers wear out faster. Under that was a pilot shirt and tie, and black shoes (again all the same design). If we were flying the owners and going to places where we were well known then we didn't bother with epaulettes. If we were flying guests or going somewhere we were not well known we would wear them; Silver bars in Europe/America, but gold bars going east (& the more the better) apparently gold bars are more respected out that way. I think the old "airline style" uniform, the double breasted jacket with shiny buttons & "wings", the hat etc etc looks very passe now, even in the airlines....
