Holiday dinners occupy an ambiguous position in the dress code landscape. They are formal enough to deserve real effort — they're significant occasions, often the most important family or social gathering of the year — but they're rarely specified as anything more than "smart" or "festive." The result is that most people either underdress (jeans on Thanksgiving, casual on Christmas) or don't think about it at all.
There is a better approach.
The Principle: Match the Effort to the Occasion
Thanksgiving dinner with close family at home has different requirements from a formal holiday dinner party at a private club or a Christmas Eve dinner at a restaurant. Both deserve more thought than defaulting to whatever is most comfortable.
The frame: dress as if you're going somewhere that deserves your best version, even if "somewhere" is your family's dining room. The people at the table will notice, even if they don't say anything, and the photographs from the occasion will reflect it.
For Men: Holiday Dinner Options
The Smart-Casual Approach (family dinner at home)
- A well-made sport coat or blazer over a clean, fitted shirt
- Dark trousers (not jeans, or well-cut dark denim if the setting is very relaxed)
- Leather shoes or clean loafers
- Optional: a casual knit tie or open collar
This is not "dressed up" in any formal sense. It's simply dressed. It shows awareness of the occasion without overreaching.
The Smart-Formal Approach (dinner party, restaurant, holiday event)
- A suit in navy, charcoal, or — for the holiday season — something with a bit more personality
- A tie or open collar depending on the setting
- Dress shoes
The Festive Approach
The holiday season is one of the few contexts where "festive" is a legitimate dress code interpretation. A velvet blazer in deep burgundy, a rich green sport coat, a tartan wool in the right proportions — these read as appropriate for December gatherings in a way they wouldn't in February. Vestium NY's sport coats in CARNET's warmer Italian cloths are particularly well-suited to this register.
For Women: Holiday Dinner Options
Holiday dinners are an excellent occasion for pieces that have personality. A tailored blazer in a rich color, a silk blouse in a deep jewel tone, a structured dress in velvet — these read as specifically seasonal and considered.
The practical note: Holiday gatherings often involve sitting for several hours at a table, potentially followed by moving between rooms, and in New York, travel on foot or in the cold. A piece that works through all of this — comfortable enough to sit in, warm enough for the season, dressy enough for photographs — is the right target.
The New York Holiday Season Specifically
New York in December has its own character. The city dresses up more than almost any other time of year — the light is right for dark fabrics and rich textures, the social calendar is packed, and the combination of formal occasions and casual gatherings creates a week-to-week wardrobe challenge.
The investment in one or two quality pieces that serve the holiday season — a velvet sport coat that goes to cocktail parties and family dinners, a silk blouse in a deep tone that works at both — is more useful than accumulating seasonal pieces from fast fashion.

Frequently Asked Questions
What should I wear to a formal holiday dinner party in New York?
Cocktail attire as a baseline: a suit and tie for men, a cocktail dress or tailored suit for women. For parties with a more festive or expressive dress code, a distinctive dinner jacket or a rich-colored tailored piece is appropriate.
Is it acceptable to wear a blazer (not a full suit) to Thanksgiving?
Yes, for a family dinner at home. A well-made sport coat or blazer with dress trousers reads as appropriately dressed for a home holiday setting. A full suit is appropriate if the occasion is a formal dinner party.
What colors work best for holiday parties and dinners?
December is one of the few times when rich, deep colors — burgundy, forest green, deep navy, dark velvet — feel naturally appropriate. The darker colors of winter wool and velvet are at home in this season.
Should men wear ties to holiday dinner parties?
It depends on the formality of the event. For a formal dinner party at a private club or restaurant: yes. For a family gathering or a more casual cocktail party: optional. When in doubt, bring a tie and decide when you arrive.
