I am due to visit a military establishment tomorrow, with the dress code on arrival to be Casual, then the next day it is into suits etc. One person's casual is another man's Sunday best so what is appropriate? I'm not thinking about turning up in trackies and a hoody, however I don't possess cream chinos and a navy blue blazer like so many other POs! More thinking towards jeans and t shirt as I have a 5 hour train journey to the place. PS: It isn't a Cavalry Regt!
