A good party requires certain conditions: low lighting, an abundance of social lubrication, a friend or two — and proper attire. Since it’s difficult to let loose when you’re chilled to the bone, your New Year’s Eve outfit should be sufficiently insulated from the winter cold. Bonus points if it’s sparkly.


A sequin dress unlike anything that has walked the Miss America stage, this sparkly Ganni number is an unexpected, covered-up take on the evening staple. Accessorize with streamlined cowboy boots, retro blue eye shadow and a boxy purse.

Definitely not a Santa suit but probably just as toasty, this floral velvet ensemble has sex appeal to rival your favorite party frock. Lipstick-red accessories and sharp stilettos raise the sizzle. Adjust to taste.

Like the Cronut, some things are better when put together. Hence the coatdress, a lexical mash-up with plenty of fashion credit — and a lifesaver for those of us who shiver in bare arms. Thigh-high boots and a red lip complete the job.
