Jose-
I dont think that if someone wears a wrinkled white shirt, their blue shirt will be neatly pressed. I am just saying that we shouldnt categorize people as being “less frum” or worse off because of their blue shirt. I am just saying that people who dress neater should be praised, rather than white shirt/blue shirt. I dont care what they wear as long as it is neat and presentable (up to a point. T-shirts and blue jeans can be neatly ironed but that, by no one’s standards, is professional dress.)
Wearing a blue shirt is not “dressing down” as many business people wear blue shirts, rather than white. Look at many professionals, or if you dont know any, look in at fancy stores. many times the blue shirts cost more than the white ones! Many suits are shown in stores with colored shirts, rather than white. White does not equal fancy, respectable ect. Dressing down means a sloppy look, a casual (non suit) attire, or vacation clothes.
