It's called professionalism, it's called showing respect for your hosts and its called representing your country in a classy manner.
Define classy- wearing a suit ? steupssss...some of the World's worst & most destructive people wear suits everyday. Class goes beyond a garment my friend. like I posted before, suits woulda been nice...but i don't think iz anything to worry about.
Besides, I think things are a little more flexible nowadays.....maybe back in the 60's all teams wore suits on arrival, but the Brazil pics are proof that that is no longer so. (unless you think that Brazil is disrespectful and unprofessional too)........
Liberate your mind a little bit......and you will realize it's probably not that big of an issue. If it were, trust me, the socawarriors would be wearing suits.... Traditional standards of "professionalism", especially when it comes to dress need not be set in stone....... and unless you were the old colonial who set the standard of professional gear back in the 1800's, your mindset shouldn't be so inflexible to such change.....unless you just like to complain and self-inflict high blood pressure......
If everyone thought so rigidly about the petty things, we'd still be living in the dark ages.....like Grande man said take a drink and cool it
just enjoy the ride.
