New York Fashion Week: The Survival Kit

Forget head-to-toe black and celery diets, our New York Fashion Week requirements are simple. You need at least one pair of sneakers for stomping the pavement and legging it between shows; a breathable, flexible body-con dress for sneaking into parties with the agility of a lemur; and a cult-carry-all big enough for your obligatory iPad but not so big as to take out Anna Wintour's left eye (maybe that's why she wears the sunglasses inside).

Here are our necessities for the week ahead — from a pocket mirror to check that your lipstick hasn't miraculously morphed into lipliner (we've all been there), to a great pen (yes, those still exist), to a certain little iPhone app that keeps on giving.
