Casual holiday parties are all about blending comfort and style. Whether you’re attending a laid-back gathering with friends or a festive family dinner, a well-thought-out casual outfit can strike the perfect balance between relaxed and refined. A modern, low-key approach to holiday dressing lets you make a statement without feeling overdressed.

Our five outfit ideas offer versatile, stylish options for men and women, proving that casual doesn’t have to mean boring.

What Do You Wear to a Casual Christmas Party?

Dressing for a casual Christmas party is about finding the right balance. For a casual look, combine comfortable staples with seasonal accents, suitable for any holiday event. Think of rich textures or muted holiday hues, for a festive yet effortless look. You can wear chunky sweaters, flannel shirts, or relaxed jackets paired with denim or fitted trousers. Accessories such as minimalist jewelry or subtle holiday-themed accents can also add a festive touch without going overboard.

When choosing colors, earthy tones like olive, burgundy, and deep gray work well for the holiday season, as do neutral shades like black, cream, or beige. Prioritize pieces that feel comfortable yet polished, ensuring you’re ready for a night of celebrating in style.

#1 Layered Hoodies and Jackets

Layering is key to creating a comfortable yet stylish outfit for holiday parties, and pairing a hoodie with a tailored jacket is a foolproof combination. Hoodies offer a laid-back vibe, while a structured jacket adds polish, creating an outfit that feels both modern and festive.

Wondering how to dress up jeans? Layer a basic shirt under the PU Cropped M65 Jacket. This black jacket’s clean silhouette is visually impactful, offering warmth without sacrificing style. Pair with straight-leg jeans and sneakers for a casual vibe, or opt for fitted trousers and boots for a more refined look.

Earthy tones like beige or olive for the hoodie contrast well with darker jackets, creating a balanced, modern holiday party outfit. 

#2 Relaxed Denim and Sweaters

A cozy and fuzzy cardigan sweater paired with relaxed denim is a timeless combination for casual holiday gatherings. This look offers warmth and comfort while maintaining a clean, put-together aesthetic. Chunky sweaters with textured details, such as cable-knit or ribbed patterns, add interest to the outfit without feeling overdone.

Try pairing a black or white polo knit sweater with our B118 Flare Work Denim. These black jeans (also available in blue) offer a relaxed fit that complements the sweater’s softness, creating a balanced look. For footwear, choose clean white sneakers for casual energy or suede boots for a slightly dressier edge.

To add a bold touch, finish the outfit with standout accessories, such as our Mirrored Studded Belt, for a festive accent. This combination works well for anyone, offering versatility for all types of holiday gatherings.

#3 Stylish Overshirts with Trousers

Overshirts are versatile layering pieces that can transform any outfit into a polished holiday look. Pairing an overshirt with fitted trousers strikes the perfect balance between relaxed and refined. Choose muted patterns like plaid or solid colors in soft materials for a festive yet understated feel.

mnml’s 100% cotton Classic Flannel Shirt, available in black, blue, and earth-colored plaid, makes a great overshirt option. It pairs easily with fitted trousers or cargo pants, creating a modern yet approachable men’s New Year’s outfit. Layer it over a plain white tee or a turtleneck for added warmth and dimension.

Complete the look with casual boots or leather sneakers, depending on the occasion. This outfit is ideal for gatherings where you want to keep things easygoing but still look put-together while still following any dress code requirements.

#4 Sleek Footwear Choices

The right footwear can elevate even the simplest holiday outfit. For casual parties, high tops or combat boots are top choices that combine comfort and style. These options keep your look relaxed without veering into overly formal territory, perfect for an office holiday party or a relaxed New Year’s Eve celebration.

White leather sneakers pair well with almost any outfit, from jeans and hoodies to trousers and overshirts. For a slightly dressier option, opt for suede or chunky loafers in earthy tones like brown or tan. If the party involves time outdoors, consider Chelsea boots, which add structure and weather resistance while maintaining a sleek silhouette.

Footwear should complement your outfit without overpowering it. Focus on clean lines and versatile styles that can transition seamlessly from holiday gatherings to everyday wear.

#5 Holiday Streetwear Essentials

Streetwear elements can add a fresh, edgy twist to casual holiday party outfits. Graphic tees, relaxed-fit cargo pants, and bold outerwear bring a modern aesthetic that feels both laid-back and festive. These essentials allow for creativity and individuality, perfect for casual parties with friends or adding them to your capsule wardrobe.

Pair a bold graphic tee with mnml’s ultra baggy Rave Double Cargo Pants. Add a lightweight jacket or flannel overshirt for extra warmth. For a monochromatic take, opt for black or neutral streetwear staples that feel elevated yet understated.

Finish the look with high-top sneakers or chunky boots to maintain the streetwear vibe. Accessories like bucket hats or minimalist jewelry can enhance the outfit further, creating a cohesive, stylish holiday ensemble.
