"I love layering a super thin, super warm vest under my coat and over whatever it is I'm wearing that day. It's a great tip because a) no one ever really sees the vest and b) it allows me to wear some of my, say, cooler coats instead of the same down parka every day. New York winters are long, and I like a little versatility in my coat game. This Nike one is on the pricier side, but it's crazy warm. And also mind-bogglingly thin. Bonus: if you decide you don't need it, it folds up into the tiniest little pouch, which then fits inside almost any purse. Extra Bonus: If you run at all (which I don't), then you'll just wear it even more!" - Verena von Pfetten, executive digital editor.
"I'm a firm believer that you shouldn't let yourself be too limited by the season when getting dressed. I layer Uniqlo's thin but remarkably warm Heattech turtlenecks under all my sleeveless and short-sleeved dresses during the colder months—and presto, they're winter-ready! They're under $15 a pop and come in at least a dozen colors and prints—of which I own no fewer than five. Staying toasty while extending the wearability of things you already own? Total win." - Elana Fishman, senior digital editor

"I almost always wear skirts so when temps drop below 20 degrees I use ilux fleece-lined tights to keep my legs warm. They look like regular opaque tights from the outside but have a cozy fleece on the inside for extra insulation. They really do the trick!" - Noelle Sciacca, associate fashion market editor
"I'm utterly chilled to the bone if my neck isn't bundled—so I always have on a HUGE, chunky, insanely long scarf. It has to be feet long so that it wraps around at least like five times. It's so, so warm, and I love how dramatic it looks. I feel exposed without it." - Megan O'Neill, senior associate beauty editor
"I'm obsessed with fleece-lined tights! Last week when the weather hit negative nine degrees, I layered these under pants one day and over tights another and they really really help. And a hat—never leave home without a hat. I recently lost this exact one and I'm replacing it immediately. Its perfect" - Julia Kalachnikoff, accessories director
"Having grown up and gone to college in Chicago, I kind of snobbishly consider myself an expert at cold weather dressing. After all, if it hits 25 degrees for multiple days in a row in January, it's considered a heat wave. I've stockpiled tons of hiking and ski socks over my years of outdoor play, and throw them on under boots to venture outside—sometimes with two pairs on top of each other if it gets really frigid. I swear by SmartWool. They're super insulated and last forever. But most importantly: don't complain! It's cold and we all know it—no need to tweet about it all day." - Maura Brannigan, digital fashion news writer
