I reject the premise. The fact is that they can.
And yes, I agree that the packaging can enhance (or diminish) the product within. I think what we wear is as much an expression of the way we feel about ourselves and the way we communicate. However, both are limited by the boundaries of our income and level of education. If someone has profound thoughts but doesn't bother with "correct" spelling, does that express that they are lazy, pay little attention to detail or don't even know what the "correct" spelling is. Aren't the profound thoughts enough to make them valuable people who merit our respect and attraction?
if someone's photos all show old jeans and stained cotton tees, maybe even ill-fitting, does that express that they are unconcerned with fashion, reject current trends or can't afford anything different. And if their clothes are beautiful, tailored, and well suited to their shape and coloring, does that make them worthier of our attraction and feelings?
I seem to have taken this off on a tangent. Apologies.
