The #1 Winter Item Every New Yorker Should Own

I moved to New York just a little over a year ago from sunny California. Considering I grew up and had spent my entire life near the beach, navigating any temperature below 50 degrees was terrifying to me. Every morning last winter, I would wake up, check the temperature outside, and ask my roommate what kind of layers I needed in order to stay warm. Remember, "cold" in California means you wear a sweater and a coat, so hold your eye rolls, please—I was new to this. After asking every New Yorker I could about the most efficient layering techniques, I was pleased to learn that almost everyone gave me the same advice. "Go to Uniqlo and buy all the Heattech you can," they said. "Wear this under everything, and you'll be warm no matter what the temperature."
