20 casual outfits that are stylish enough to wear to a New Year's Eve party

It's the biggest party night of the year, but that doesn't have to mean wearing stuffy suits, high-maintenance cocktail dresses or uncomfortable heels. Whether you're staying in for a Zoom gathering or enjoying a casual party with friends, you can look put-together and party-ready without sacrificing comfort. Welcome the new year feeling your best by adding a little sparkle to your time-tested favorite looks.

In this article: Men's Lands' End Classic Fit Fine-Gauge Supima Cotton V-neck Sweater, In'voland Women's Plus Size Sequin Jacket and Urbanfind Men's Slim Fit Lightweight Bomber Jacket.

Casual New Year's Eve party outfit ideas

Whatever you choose to wear for your New Year's Eve party, don't forget the sparkle. New Year's Eve is all about sequins, shiny satin and shimmery velvet. Try a festive tank top, or simply dress up your favorite sweater with a statement necklace or earrings. Consider swapping out your purse for a metallic or beaded clutch.

Since the start of a new year is a special occasion, consider trying one of your favorite casual wardrobe staples in a dressier fabric. Swap your go-to denim jeans for stretchy yet structured ponte pants, or splurge on a cashmere sweater.

If you're going out, don't forget layers to stay warm in winter weather. A velvet blazer is a trendy and stylish way to dress up even the most ordinary outfit and keep warm at the same time. Wool overcoats and down coats can both be easily dressed up with elegant scarves if you want even your outerwear to look festive.
