The culture has changed and evolved. Some can choose to live in the past. But no reason to force others to do so. A comfortable pair of jeans or shorts and a comfortable shirt or T shirt is just fine as far as I am concerned. If someone chooses to wear something different I would possibly glance strangely at them and then again I might not. In a society with increased diversity one has to allow greater variance what is acceptable attire.
it does make me wonder... it is now legal for women to walk around
topless
(i.e. showing their breasts) in New York City.
does that apply to women who choose to board Amtrak trains at Penn Station?
(only asking about the legal aspect of it and only pertaining to boarding Amtrak trains)
