Cruise Ship Dress Codes: What to Wear on Every Cruise Line (2026)

What to Wear on a Cruise: The Complete Dress Code Guide

One of the most common questions first-time cruisers ask is: what do I actually wear on a cruise? The good news is that cruise dress codes have relaxed significantly over the years. Gone are the days when every dinner required a three-piece suit or a floor-length gown. Today, most cruise lines aim to keep things smart while letting you feel comfortable on holiday.

That said, every cruise line is different. Cunard still embraces the glamour of black-tie evenings. Virgin Voyages has no dress code at all. This guide breaks down what to expect on each major cruise line so you can pack with confidence.

Formal and Elegant Nights

Most mainstream cruise lines still host one or two formal evenings per seven-night sailing. These are often called Gala Nights, Elegant Evenings or Evening Chic, depending on the line. They are usually held in the main dining room, and many guests look forward to dressing up as part of the cruise experience.

What to Wear on Formal Night

• Men: dark suit, tuxedo, or dinner jacket with dress shirt and tie. Smart dark trousers with a blazer also work on most lines.
• Women: cocktail dress, evening gown, dressy jumpsuit, or smart separates. Accessories and heels are common but not required.
• Children: smart clothing. A collared shirt and trousers for boys, a party dress for girls. Most lines are relaxed about children's attire.

How many formal nights? A typical 7-night cruise has 1 to 2 formal nights. Longer voyages (14+ nights) may have 3 to 4. Short 3 to 4 night sailings usually have one or none.

If formal nights are not for you, most ships offer alternative casual dining in the buffet or speciality restaurants where no dress code is enforced.

Smart Casual: The Most Common Dress Code

On most evenings, cruise lines ask guests to dress smart casual for the main dining room. This is the standard you will encounter most often, and it is less intimidating than it sounds.

What Smart Casual Means on a Cruise

• Men: chinos or smart trousers with a polo shirt, button-down shirt, or light sweater. No tie required. Clean trainers or loafers are fine.
• Women: sundress, blouse with trousers or a skirt, smart jumpsuit, or a casual maxi dress. Sandals or flats are perfectly acceptable.

Think of it as what you might wear to a nice restaurant at home. Not jeans and a t-shirt, but not black-tie either.

Casual: Daytime and Pool Deck

During the day, all cruise lines are relaxed. Shorts, t-shirts, sundresses and swimwear (at the pool) are all perfectly fine. Most ships have no daytime dress code outside of the spa or fitness centre.

• Pool deck: swimwear, cover-ups, flip-flops, sunglasses. Standard holiday attire.
• Daytime restaurants: shorts and a casual top are fine in the buffet. Some sit-down lunch venues prefer no swimwear.
• Port days: comfortable walking shoes, breathable clothing, sun protection. Dress for the destination and activity.

Themed Nights

Many cruise lines host themed evenings that replace or supplement the traditional dress code:

• White Party (Norwegian): an all-white themed deck party. Pack a white outfit if sailing NCL.
• Pirate Night (Disney): a Disney tradition where guests dress in pirate costumes for an evening deck party and fireworks. Bandanas are provided.
• 70s or 80s Night: some lines host retro-themed parties. Participation is optional but adds to the fun.
• Gala or Captain's Night: the most formal of all themed evenings, often coinciding with the Captain's welcome reception.

Dress Code Comparison by Cruise Line

What NOT to Wear

While dress codes have relaxed, there are still a few universal restrictions across most cruise lines:

• No swimwear in restaurants. This applies to all dining venues, not just the main dining room.
• No sleeveless vests or singlets in the main dining room on most lines (men).
• No flip-flops in the main dining room during dinner on many lines.
• No shorts in the main dining room at dinner. Even on casual nights, most lines draw the line here.
• No bare feet anywhere except the pool deck.

If in doubt, keep it simple: if you would not wear it to a decent restaurant on land, leave it for the pool deck.

Packing Tips: How Many Outfits Do You Need?

Smart packing is all about mix-and-match. Here is a practical approach for a 7-night cruise:

• 1 to 2 formal outfits if your cruise line has formal nights.
• 3 to 4 smart casual outfits for evening dining. Mix tops and bottoms to create variety.
• 3 to 4 casual daytime outfits including shorts, t-shirts and lightweight layers.
• 2 swimsuits so one can dry while you wear the other.
• Comfortable walking shoes for port days, plus sandals and dress shoes.
• A light jacket or cardigan. Ships can be air-conditioned and evenings on deck are breezy.

Pro tip: many experienced cruisers pack neutral-coloured basics and use accessories (scarves, jewellery, ties) to change up their look each evening without overpacking.
