What you should wear to a New Year’s Eve (NYE) dinner depends heavily on the venue and the dress code. NYE generally calls for a festive, slightly elevated look, with popular choices including sequins, velvet, and jewel tones.
Here are outfit ideas tailored to different types of dinners:
Formal or Black-Tie Dinner

A formal dinner at an upscale restaurant or a gala calls for elegant attire.
Men: A tuxedo or a sharp, dark suit is best. A black tuxedo with a white dress shirt and a bow tie is a classic option, or you can incorporate a modern twist with a velvet dinner jacket in a deep color like burgundy or emerald green. Complete the look with patent leather dress shoes.
Women: A floor-length gown or a chic cocktail dress is appropriate. Opt for rich fabrics like satin, silk, or velvet, potentially with shimmering or beaded details. Pair with sophisticated heels and statement jewelry.
Smart Casual or Semi-Formal Dinner

This is the most common dress code for a dinner with friends or family at a nice restaurant. It’s an opportunity to blend style with comfort.
Men: You can wear a formal shirt or a fine-knit jumper with dark chinos or tailored slacks. A sport coat or blazer can add a polished touch. Loafers or chukka boots will complete the look. Avoid overly casual items like t-shirts or athletic trainers.
Women: Consider a stylish jumpsuit, a sequin or metallic skirt paired with a sophisticated top (e.g., a leather jacket and mockneck top), or a fit-and-flare sweater dress. Dark wash, dressed-up denim can even work if paired with a silky cami and pointed-toe boots.
Casual House Party or Cozy Dinner In

For a relaxed evening, the focus is on being comfortable while still feeling festive.
Men: A well-fitted polo or button-down shirt layered under a quality knit cardigan or jumper, paired with dark chinos, is a neat but comfortable outfit.
Women: Trade everyday sweats for cozy, but special, options like shimmery pants or a comfortable knit dress.
