Areivim, you said
“First class by today’s standards is a white shirt & dark suit (men). Just walk the streets of Manhattan. Anyone that’s a who’s who or is at least trying to look the part will be dressed in this formal attire. Now the hat is the only part left to argue about.”
No it isnt, you will see people wearing dark suits and dress shirts of many assorted colors.
There is also no real argument that a black hat is NOT considerd normal, formal or proffesional attire nowadays, its just considerd wierd.
