Some people have style, some don't.
You know it when you see it.
And some people find the entire concept of 'style' (especially dictated by someone other than themselves) to be the height of pretension.
Chacon à son goût, as Prince Orlovsky says....
For myself, I dress for comfort, but respect the fact that I will be spending several hours in close physical proximity to other people. Like many others, I would never enter an airplane cabin without being well-groomed and wearing clean, neat clothes. However, I personally never fly with just a t-shirt as my only upper garment, because I consider t-shirts to be underwear, and my mother taught me to not walk around in public with my underwear showing.
