Finding great style is somehow easier in New York, because certain parts of town have combined the so called upper class with people, who have money as well as affection for fashion.
Even if fashion is constantly changing, it is also true that the basic pieces always remain the same, so it is smart to have them; they are especially important in this year's winter, which is extremely clean and elegant.
I'm sure that the LBD has a special place in every woman's wardrobe; I have a couple of versions myself and I still find myself buying new ones, simply because they come in so handy.
