A politician in New Orleans is trying to ban people from wearing pajamas in public. "Today it's pajamas; next it will be underwear tomorrow," the politician makes a point. I know I do not want to see people in their underwear.
I do think that it is a huge jump from pajamas to underwear. Some people say that wearing pajamas in public is "like wearing a swimsuit to a business meeting." What happens when your extremely sick and must go to the doctor's office? Even if your not extremely sick, how does another's wearing pajamas affect you?
I think that this is all just a matter of opinion. Wear pajamas if you want, and if you do not then don't. Don't try to make everyone because it's not what you want.
