This is a funny thread so couldn't resist putting in my penny's worth
Depending on where I have flown I have adopted the "local culture" as far as uniform (or no uniform), that is to say I have been a team player and fitted in.
When working for a more formal employer I have resisted full Dinner Jacket and Top Hat but quite honestly I don't care if I have to dress up as Mickey Mouse or fly in the nude as long as it is a good place to work and I get some decent flying experience.
I have noticed that tie and bars are normally found where people are very focused on preparing for an airline career, I have also seen the results that these company's get (very successful). Why do they get these good results ? I think because they are instilling professional attitudes, pride and discipline from day 1 with an attitude that you may as well start as you mean to go on and "dress for success"
In the US there is a different more relaxed culture with smart slacks and polo shirts which is very "relaxed executive" but achieves equally good results.
Moral - If you don't like the local garb then leave and find a tribe that you do like - next time you are at the airport lookout for the Mohican with the tie dyed tshirt and face piercings who is captain of your long haul flight !!!!
