Having read this thread form start to finish, I have to say I find it a little bit scary that such debate has been entered into.
I'm not sure if we're all aware, but we live in a free country, and we are allowed to dress how we like. Sure the Qantas Club and Other QF lounges publish certain "standards" that they believe to be acceptable, but at the end of the day, they (lounge dragons) are the judge, jury and executioner with respect to that decision.
I think it's perfectly reasonable to wear any form of comfortable casual clothing when in the lounge or flying on an aircraft. How can anyone possibly be offended by someone wearing stubbies, singlet and thongs? Would you also be offended if you saw someone wearing a suit that was from Lowes rather than Hugo Boss?
Travelling is best done with the traveller feeling as comfortable as possible. As long as I'm not seeing anyone's private bits, then I'm not going to be offended. I wear what is comfortable for the journey I'm taking. I don't care if I'm flying J (usually), or Y, I dress in the same way. When I fly J, I'm no better than those in Y, and when I'm in the lounge, my clothes don't make me any more or less intelligent than anyone around me. (as was implied by earlier poster)
This type of snobbery is crazy. It takes all sorts, from all walks of life, and all variants of fashion to make up our society, which are in turn, the travelling public... There are way more important things to care about.. If someone's behaviour is offensive, then sure get upset, but you simply can't be offended by someone dressing too casually.
I travel often, for both work and pleasure. For work, I'm in a suit, and it's a miserable and uncomfortable ride (not to mention HOT).. For pleasure, I wear casual. Many a trip back from BNE on a Sunday afternoon has seen me in the BNE J lounge in shorts and a singlet (surf style), and there have been MANY other patrons dressed similarly. BNE is a hot city... polo shirts and chinos (YUK) are too warm for me (and iMHO one of the most unfashionable items of clothing EVER), but, I'm not bothered if you want to wear them. I'm not judging you.. I'm too busy not actually caring !!
One thing this thread has made me conscious of though, is that next time I'm sitting comfortably in the BNE J lounge on a Sunday afternoon, I may very well be being judged, and causing offense while minding my own business....
