There's a version of New Year's Eve that happens in a crowded bar in a cold city, and there's the version that happens somewhere warm — at a table on a waterfront terrace, or a beach club with a good sound system, or a rooftop in Miami watching the fireworks go up over the water.
The people who choose the second version tend to know what they want. They booked the trip months ago. They picked the restaurant before they landed. What they sometimes haven't figured out is what to wear — because NYE at a beach resort occupies a specific territory that most style advice doesn't cover. Too casual and you're underdressed for the room. Too formal and you're wearing a tuxedo on a dock in 82-degree weather, which is its own problem.
Here's how to get it right.
The Dress Code: What "Festive Resort Casual" Actually Means
Most beach resort venues describe their New Year's Eve dress code as something like "festive," "smart casual," or "resort elegant." These are vague terms that mean different things depending on where you are.
What they consistently exclude: board shorts, tank tops, flip-flops, athleisure, and anything that reads as daytime beach. What they consistently allow: swim trunks worn with a collared shirt, lightweight trousers, linen or cotton button-downs, and clean sandals or loafers.
The practical standard: dress one level above how you'd dress for a nice lunch at the same venue. If lunch is trunks and a linen shirt unbuttoned, NYE is the same trunks with the shirt buttoned and a pair of loafers instead of sandals. If the venue is more formal, add lightweight trousers and swap the trunks entirely.
The goal is to look like someone who dressed intentionally for the evening — not like someone who came from the pool and stayed.
For Men
The Resort Tuxedo
This is what works at nearly every beach resort NYE without overthinking it: a tailored swim trunk, an Oxford cotton shirt buttoned most of the way up, loafers or clean leather sandals, and nothing else that needs explaining.
Le Club Original's Oxford Cotton Shirt ($99) — available in White, Aqua, Beige, Sky, and Pink — reads as dressed up without being overdressed. White is the cleanest choice for NYE. Aqua or Sky works if you're leaning into the coastal context. The Oxford weave has enough structure to feel like an event without requiring a jacket.
Pair it with swim trunks in a solid or subtle print — not the boldest print you own. This is the night to let the shirt be the statement.
When the Italian Linen Shirt Is Enough
At a more relaxed beach club or an outdoor NYE setting — an open-air terrace, a bonfire on the beach, a boat party — a linen shirt worn buttoned and tucked in (or half-tucked) is the right level. It breathes, it moves, and it looks right in warm air in a way that stiffer fabrics don't.
Le Club's Italian Linen Shirts ($115) — the Classic in White or Light Blue, or the Peter in Navy or Sage — work at this register effortlessly. The White linen shirt on NYE, with the right trunks, is hard to argue with.

On the Swim Trunks
NYE is the right moment for a cleaner, more tailored trunk. Avoid the longest, loosest option in your rotation. A 5.5" or 6.25" inseam in a solid color or a subtle, contained print works better than a bold tropical pattern for a formal dinner setting.
For Women
New Year's Eve at a beach resort gives women more room to work with — and also more room to get it wrong in both directions.
Too casual: wearing the same coverup dress you wore to lunch. It'll do, but it reads as an afterthought on the one night of the year you want to look like you made a decision.
Too formal: a full-length gown or anything that belongs in a ballroom. The beach context matters. Stilettos on a dock are a safety issue and a shoe-ruining one.
The right register: a dress that could be described as "festive" without quotation marks. A silk or satin slip dress, a linen midi dress in a vibrant color, a structured wrap dress, a two-piece set that reads as an outfit rather than a swimsuit. Something that moves well in warm air.
The women who get NYE at a beach resort right tend to look like they dressed for the evening they're actually having — not for a different version of it somewhere else.

By Destination
The right outfit shifts slightly depending on where you are.
Miami / South Florida: The most dressed-up of the beach NYE options. Miami's waterfront venues lean toward smart casual to semi-formal. White linen or Oxford cotton on men; a proper dress on women. Loafers or leather sandals; heeled sandals.
Caribbean (Turks & Caicos, Bahamas, St. Barts): Resort elegant, which in practice means well-chosen resort wear. The trunks-and-Oxford-shirt combination works at nearly every venue here. Women have more latitude with coastal prints and wrap dresses.
Mexico (Tulum, Los Cabos, Cancún): Tulum leans bohemian — linen is more at home here than Oxford cotton. Cabos and Cancún resort zones can be more formal. Know your venue.
Florida Keys: The most relaxed of all. A linen shirt over clean trunks is genuinely acceptable at most venues. The Keys do not stand on ceremony about dress codes.
The Part Most People Get Wrong
Shoes.
Men show up to NYE dinner at a nice waterfront restaurant in the same rubber flip-flops they wore to the beach that morning. It's the one thing that will get you turned away at the door or just make you look like you didn't try.
Loafers work everywhere. Leather sandals — not rubber, not foam — work at most beach resort venues. Clean espadrilles work at casual settings. Pick one. Pack it alongside the dress outfit rather than assuming you can make beach footwear formal.
Frequently Asked Questions
What do you wear to New Year's Eve at a beach resort? The dress code at most beach resort NYE events is festive resort casual — more intentional than a regular beach dinner, less formal than a black-tie event. For men: tailored swim trunks with a collared button-down shirt (Oxford cotton or linen), loafers or leather sandals. For women: a dress that reads as festive without being a gown — a silk slip, a structured wrap dress, or a linen midi in a vibrant color. The key for both: shoes that are not rubber flip-flops.
Can you wear swim trunks on New Year's Eve? Yes, at most beach resort venues — paired with the right shirt. A tailored swim trunk with an Oxford cotton or linen shirt buttoned up, and clean leather shoes or loafers, satisfies the dress code at nearly every beach club and resort restaurant on NYE. The trunk should be on the shorter, cleaner side (5.5"–6.25" inseam) rather than the longest, loosest option you own.
What is the dress code for NYE at a beach club? Beach clubs typically describe their NYE dress code as "festive," "smart casual," or "resort elegant." In practice this means: no board shorts, tank tops, or athletic wear; swim trunks with collared shirts are generally accepted; loafers, leather sandals, or espadrilles over rubber flip-flops. When in doubt, call the venue — most will tell you exactly what they expect.
What should men wear to a New Year's Eve dinner on the beach? A tailored swim trunk in a solid color or subtle print, an Oxford cotton or linen shirt buttoned up, and loafers or leather sandals is the right outfit for most NYE beach resort dinners. White Oxford cotton or white linen is the cleanest choice. The overall effect should read as dressed for the occasion — not as someone who came from the pool.
What should women wear to a beach resort on New Year's Eve? A dress that reads as festive without requiring a ballroom — a silk or satin slip dress, a structured wrap dress, a linen midi in a vibrant color, or a two-piece set that reads as an outfit. Wedge heels or heeled sandals for venues with uneven terrain. The goal is to look like you dressed for the evening you're having, not a different version of it elsewhere.
