It is not so much the "clothes" per se, but the overall appearance. I have seen slobs beyond belief in suits with manners that correspond with their appearance and others in what was very modestly priced clothing but put together well, height and weight within a normal range, and with solid manners and self dignity.

Still, there should be some decorum of dress for a F class cabin like no tank tops for the men and no Daisey Dukes for the Women. And it never ceases to amaze me seeing 300 pound men with flab abound wearing a tank top and believing that some how they look "sexy" for the ladies. Yuck
