Theory Tubular Tank from Otte NY
"I'm from Miami and admittedly a winter wimp, I've learned that the best way to stay warm is layers. I am usually wearing tights under my pants and Theory tubular stretch tanks under all my tops/sweaters."

Reed Krakoff's Boxer Bag from Net-A-Porter
"I'm a bag fanatic! I switch up my bag quite often and in the wintertime I usually prefer a larger bag — big enough to stuff my gloves, scarf, hat etc."

The iPhone 5
"I am glued and borderline addicted to my iPhone. That little phone is just incredible…it helps me do my job from anywhere, check my Instagram, read The New York Post, and (bonus!) takes the best pictures of my kitten Frankie."
