Having just returned I want to dispell the myth that New Yorkers wear all black. They simply don't. They do however tend to wear dull colors and nothing too bright except for children. They wear shorts, t-shirts, tennis shoes, and tank tops. I saw lots of locals dressed this way. I know you want to know how I know they were locals and not tourists...The people I'm speaking of were selling art on the street, working in shops, passing through buildings with security keys, etc. Our Big Apple Greeter was wearing a plaid shirt, khaki pants, and tennis shoes. The two men sitting next to us at dinner one night were dressed similarly, and one of them told us he managed a building on the block. I did however choose to always wear black shoes and black capris or skirts. I am glad I did simply because we got so dirty from walking around all day.
