I agree with dressing for the occasion. But this is subjective and cultural.
Did Paul carry around walking clothes and Sunday clothes? Probably not. That was not the custom.
My cousin died last month. I wore jeans and a short sleeve button up shirt.
I think I wore jeans and a nice shirt to the last wedding I attended.
For church I dress nice. But nice is subjective (that guy you said was blasphemous for praising God while wearing a black t-shirt was dressed nice to me).
For work I wear jeans and a shirt with a pocket (reading glasses). In the summer its shorts and the same shirt. Never anything I would hate to loose if it becomes contaminated.
Eating at a nice restaurant? Jeans and a nice shirt. Thankfully the "fine dining" today foes not have the dress code of yesterday. I tend to drop food occasionally.
@Charlie24. I get where you are coming from. I am by no means saying you should not dress as your conscious dictates. We all have our idea of what is ideal.
I am, however, saying that you should not impose your conscience on other people.
Is the time changing from your ideal culture? No. It has already changed.
And you have with it. You were sporting the Gavin Newsom look ;-).
Wearing a suit without a tie has become acceptable because the culture of the world has changed. But this became very popular in the 1970's with the youth (a worldly shift in acceptable fashion). More recently it has made a comeback as business casual.
Now it is business attire to wear a jacket over a t-shirt and jeans.
Weird....huh?
One day it will be business attire to wear blue Jean shorts with tank tops. But don't worry...I doubt we will be around to see it.
